Preliminary Spoiler
Aug 22, 2013
Mod Edit: Minor Spoilers mentioned.

I'm just going to say this straight away: These kind of animes bring out the silly little girl in me. And as I'm a 19-year old guy, it's kind of an unexpected thing, even for me. And I mean this in the most positive way possible.

"K-On!" follows the story of Hirasawa Yui, a girl who lives a life similar to your average person on the net, except for the internet part. It's difficult to explain without using the words "carefree" and "lazy". In a way, she probably reflects a majority of people I know, including myself, except for the fact she ...

This review is going to be broken down into the 5 parts that MAL focuses on with each section getting critiqued.

As you know by the description on the anime's page, K-on is suppose to be about Yui Hirasawa and joining of saving of her high school's light music club, with the problem being that Yui has never read music or knows how to play a guitar. Slowly a few of these problems get cleared up but the main bulk of the plot goes no where whatsoever. You can come in at any episode and still get what's going. The anime is heavy on the theme ...

If K-ON! is the future of slice-of-life moe anime, then the genre is dying. Now, I myself am personally a great fan of the niche genre and have delighted in viewing many anime falling under it, no matter how silly or inane. That's because I don't mind having to turn off my brain to enjoy anime, but I expect to be compensated for doing so, be it by making me laugh, warming my heart, or leaving me with something to remember. K-ON! splendidly failed in all three ways multiple times throughout, and came off as a shoddy effort all around.

Because a slice-of-life moe series is ...

K-ON! is inconsequential fluff. One might compare it to popcorn or cotton candy: a tasty treat, but if you're looking for a meal, it will leave you looking for something more substantial after it's done.

K-ON! follows the tried and true formula of cute girls doing cute things. Based on a 4-koma comic, the series is about several high school girls who form (technically join, but all the previous members graduated) a light music club and follows their activities. The music itself often takes a back seat to the antics of the girls, and audiophiles may find themselves somewhat disappointed if they go in expecting detailed ...

I picked up "K-On!" envisioning it as some kind of healing, mundane slice of life in the same vein as "Aria the Animation", something nice and gentle that would help soothe my severe withdraw symptoms brought on by finishing "Hikaru no Go". Even though on the surface I mostly got what I was looking for (it is mundane, and it is a slice of life), the end product was a huge disappointment. It's a bit like one of those twisted fairy tales in which some greedy guy makes wishes to the devil or a genie or something. Even though his wishes are all granted, ...

Before I begin this review it must be noted that I am not a moe hater. Shows centralized on moe are fine so long as it succeeds at its task. What is not fine is a show that is completely false advertising.

Coming into K-ON! you would expect to see a show about girls getting into a band and watch them enjoy the experience of learning to play music. While we don't exactly expect for them to get all that dramatic or serious all the time, it's still nice to see the struggles of learning to play music, the effort it takes to get good, and ...

Time and time again, Kyoto Animation has gained the hearts of the people and has quickly become a company that seems to turn whatever they animate into an instant cultural frenzy. For K-ON! this is no different. Based on a 4koma manga by Kakifly, K-ON! went from practically unknown to massive super hit in only a matter of days. However, putting aside its massive popularity, how does K-ON the anime fare? Read on and find out.

Before I start the review there are some important questions you should ask yourself:
1. Do you hate animes with extreme amounts of moe?
2. Do you hate slice of life animes?
3. ...

There are far and few fabulous things in this world.

But in the midst of all the moe puke and unfabulous whatever-dere, otaku pandering nonsense comes a series that manages to both please the fanbase and stand on its own two feet. No, I'm not talking about my reality TV show--I mean K-On.

Yui, the resident retard-moe, has herself an unfabulous predicament: she needs to join a club. What a coincidence that Moe, the tsundere (i.e. mood swinging bitchy stick in the mud) bassist and her best friend Ritalin the genki drummer have a club that needs members. The light music club. By "light music", think ...

Preliminary (12/13 eps)
Story: 5 ( It almost feels like the show has a bad case of A.D.D. when it skips the important stuff. Trust me, they do it ALOT.)

Art: 7 (I believe most of the time and effort and money went in to replicating the girls instruments with their real life counterparts.)

Sound: 9 - (If you hate j-pop/rock, feel free to deduct 3 points)

Character: 8 (one phrase: Moe moe~ Kyu!, deduct 6 points if you hate moe)

Enjoyment: 9 (Its obvious as to why such a short and simple show is so appealing to the masses)

Preliminary (4/13 eps)
After reading a review of this series while comparing it to Lucky Star, I couldn't help but twitch in all of my facial muscles used for frowning and decided to write my own review.

K-ON! is, simply put about a group of four high-school girls who join the schools light music club for various reasons and with various degrees of enthusiasm. However, as members of the light music club, great responsibility is put on them. As of episode 4, nothing seriously mind-bending has happened, but the individual characters drives the story forward in their own fashion, rather than some evil villain who pulls all the strings.

Rather ...

I can write many single words to describe my feelings towards K-on, but I'll try to convey them in a small review.

Story? What story. There is none. It is a slice of life show and I really mean they just take a slice out of anything they find amusing (which I probably didn't) and put it in the show. A day in the life of a high school girl who happens to be in the light music club. Some of these "slices" though tend to lead to very boring and I mean boring episodes. I think I was asleep half of the season watching this ...

As a guy who enjoys many varied animes from Ah My Goddess to One Piece, I'm quite willing to adapt to and enjoy many genres.

Many animes have "moe" characters in it to either please viewers or just to add a touch of cuteness. However, K-On misses the point entirely. In fact, as soon as the first episode begins, the "moe" (read: retardedness) seems almost FORCED onto you. By the time I was 10 minutes in, I was drowning in a see of concentrated lame attempts at cuteness.

Seriously, this anime will only please girls very fond of "OMG SO CUTE :3". For the rest of us ...

Having spent most of my summer engulfed in the world of engineering, I figured a series based on music would be a great distraction. Tack on some hyper-energetic high school girls and a slice-of-life setting, and K-On’s light-hearted charm naturally piqued my interest.
This premise is undoubtedly what makes K-On so captivating. As a whole, the show never attempts to step beyond its means; it sets itself out to be simple fun and undoubtedly succeeds. Despite operating off a number of base gags and jokes that find themselves revisited from episode to episode, the series never seems to drag. Ultimately, the musical aspect of the show, ...

Some shows have stories that are complex or linear. Some have stories that are downright hilarious. And K-on.......uh......umm.......whats the story again? Does anyone even know the story of this show, anyone?! No, well thats awkward. K-on, the show that has cute ass girl who drink tea, eat and have fun.....and play music. Not really but you could put that in a sense. What is this show about and the point of it? Absolutely nothing, but not in a bad way. This is that type of moe-show thats there in case you wanna sit down and relax, it isn't a show that keeps you on your ...

A lot of criticism surrounds K-ON! It is usually based on that it supposedly doesn't deliver what it should. Well I'm going to say that's all rubbish. What makes K-ON! stand out is simple: It's refreshing. (A word I will be using a lot in this review)

The story is great for providing that breath of fresh air not found in similar programs. The moe aspects are what makes this a really nice watch, and the humour on top is even better. You shouldn't be disappointed because it's going to put a smile to your face. Unless... Unless you were hoping K-ON! was going to be ...

There are anime that build a huge hype around them and turn out below average. Then, there are anime that do the same but they still manage to meet expectations of their fans. Which group does K-On! belong to? In a way, both. While it completely manages to please fans of slice-of-life and comedy manga, even some people that love K-On! admit that nothing actually happens in it. That’s where people that like their anime with plot facewall to oblivion.

Story: 1/10
Why such low rating? Because there is nothing to rate. The only signs of story were at the very beginning and even then ...

K-ON! is a slice of life anime with no real story. Its about the day to day lives of cliche moe characters that form a band and do everything BUT actually play music.......for the most part.
The majority of the time is wasted with the characters eating cake and talking about a bunch of random nonsense that isn't delivered as good as in anime like Lucky Star, neither is it as funny, and it gets old pretty fast. The final episode (12 or 13 doesn't really matter what you consider the final) is pretty anti-climatic (like most slice of life series) and just leaves much ...

Preliminary (2/13 eps)
Based on the 2 episodes so far...this show can be summed up in 10 words :
Lucky Star without the otaku reference and with music instruments.

For a more in-depth look, read on.

Well...its about 4 girls joining the light music club hoping to start a band of their own and perform in front of a sold out audience (presumably). There is a plot here (somewhat) unlike Lucky Star, but that plot is loose and gets diverted at certain times. In a nutshell, the plot will be followed loosely so if you want a powerful story, you ain't getting one.

The art is appropriate for this kind of show. ...

K-on is an anime that caught my attention I was simply being presented with very bad animes, and when I picked up K-on to see it and thought it was a bad anime, it completely surprised me, and when I completed it it felt like an emptiness inside of me it was filled by some incredible, making it to put like favorite, in this Review I will try to pass on my feelings and some observations about K-on.

Now let's talk about something that is very present and even today many memes are made, which is animation, many may say that K-on animation is the worst ...

Another blockbuster from Kyoto Animation studio. Forming a music band that is a pretext to eat cakes and drink tea in nice atmosphere. Enjoyable and positive comedy with big accumulation of moe.

Kyoto Animation has at least two recognizable anime series. After Lucky Star and The Melancholy of Haruhi Suzumiya we have K-on. This time we don’t have loli student who talks about food or girl who search for aliens. This time the pretext is… a music band. Yes, Kyoto Animation knows how to attract millions of otaku. For K-on has so much fans as adventures of Haruhi or Konata and the amount of bayed ...
