Katekyo Hitman Reborn is an outstandingly well made anime. I definitely recommend that you watch it if comedy and action applies to your genre of choice.
At first glance, Katekyo Hitman Reborn may seem boring. The major flaw of the anime is that it absolutely misleads you, and it completely deceives you into either a) dropping the anime or b) thinking the anime is lame, when it isn't!
The first 20 episodes may mislead you to drop the anime, just like it misled me, because of its fillerlike episodes. You will most likely tell yourself "Wow, this is really lame. What's the point of all this?"
That's what I thought, but I gave it a chance. (And I'm SO glad I did. Katekyo Hitman Reborn is now my absolute favorite anime.)
The beginning is kind of slow and different from the rest of the later episodes, because apparently KHR was initially meant to be a gag anime - it was supposed to be something funny and comedic. The anime took a different turn as you progress to episode 20 into something more serious.
The first 20 episodes is merely a /long/ introduction to the anime. It's worth watching though, because you get to be familiar with all the characters. They are all likeable! If you decide to watch Katekyo Hitman Reborn (and I hope you will!) you should decide whether you like it or not, after 25 episodes or so. It's only fair, right? All animes have their flaws; and it's flaw, in my opinion is that they don't give it a decent start. If you do not have the patience for that, then this anime may not be for you.
Katekyo Hitman Reborn deals with the mafia. Tsuna, the *main* character, is in the next line to be the 10th boss for the Vongola Family~ (one of the many families in the mafia.) Reborn, a hitman, and also a baby (hehe), travels from Italy to Japan to tutor Tsuna to become a worthy boss for the Vongola Family.
From then on, Tsuna's adventures and what he experiences are endless-- but they're all interesting. Over the course of the anime, Tsuna grows and matures, and becomes really strong; fighting his enemies and getting stronger each fight he experiences. The fights he encounters are well made, and they WILL keep you at the edge of your seat. Tsuna isn't the only one fighting, though-- he also has a "family"-- his comrades, if you will, and the battles they encounter are endless.
The art is well made; I don't think there is much to complain about it.
It isn't outstandingly good, nor is it horribly bad to a point where you have to shield your eyes. The characters are wonderfully drawn and are all unique in their own ways. The art progressively gets better as you further get into the anime.
The sound is absolutely AMAZING. It deserves an 11/10, as opposed to a 10/10.
I loved all of the openings, and endings-- I never once had to skip it; and that's kind of rare, considering the fact that I'm absolutely picky with my music.
The soundtrack is amazing as well, there is a couple of them for EACH character (well, the main characters, anyways.)
They have a soundtrack for every different scene in the anime, and it is absolutely positively pleasing to the ears. Everything about it is EPIC!
The characters are very well portrayed; you can't help but love all of them (well most of them anyways.) They change greatly over the course of the anime and it's worthwhile to watch them grow up.
I love Katekyo Hitman Reborn! I love everything about it; it makes me laugh until I fall off my seat and look like a loser, it makes me sad as they go through their hard times, it makes me happy as they overcome their obstacles-- and so on.
I can ramble on forever about how much I love the anime, but I'm going to end now, before I end up typing a ten page paper.
Katekyo Hitman Reborn is an AMAZING anime as I mentioned a billion times (well not really, but let's pretend.) I highly suggest that you go off and watch it right now, but I can't tell you what to do. It's ultimately up to you.
Everything about it is amazing- it's storyline, (although it may seem boring at first) it's art, it's sound, it's characters-- it's everything!
