My manga list is incomplete and so I've given up on making one. It would simply take too long as the list would be hundreds and hundreds of titles long, most of which I cannot remember unfortunately.
When given the option to watch the anime or read the manga, I always choose to watch the anime first. This is because manga are usually more detailed than the anime version which tends to be a more synoptic of the former so I watch the inferior version storywise first then proceed for the detail. Furthermore, I think a lot of series benefit greatly from animation, in particular action, horror, shounen etc. so I can fully enjoy the experience by choosing the correct medium.
"It is absurd to divide people into good and bad. People are either charming or tedious." - Izaya Orihara
“If the system possesses the power of life and death over you… you’re no longer a human. You’re livestock. No matter how hard a rancher tries to pretend otherwise, they never recognize their livestock as friends. It’s a mystery to me… How is it that these people, treated as livestock in this boring society, have not tried at all to destroy it?" - Shougo Makishima
"If I had to cooperate with that guy in a match, I'd rather receive, spike and toss all by myself." - Tobio Kageyama
"I'm writing this letter because I don't want the 16-year old me to carry a lifetime of regret." - Naho Takamiya (Orange)
"I don't do anything I don't have to. What I have to do, I do it quickly." - Oreki Houtarou (Hyouka)
"We ultimately fear what spawns from within us." - Shun Aonuma (Shinsekai Yori)
"All the cards are in my hand." - Mikado Ryuugamine (Durarara!!)
"To me she represents nothing less than the very secrets of the world." - Takao Akizuki (The Garden of Words)
10 = The pinnacle of my anime experience. No more satisfaction can be derived from any medium of entertainment - anime, manga, book, movie etc. My absolute favourites. (eg. Shinsekai Yori, Durarara!!)
9 = An absolutely fantastic anime that presented themselves to be stellar in all factors I care about. In some cases, hardly distinguishable from my 10s. (eg. Fate/Zero, Haikyuu!!)
8 = Excellent. These represent some of my best experiences in anime in some genres. Marathon material. (eg. Shigatsu wa Kimi no Uso, Oreigaru S2)
7 = A great show. Captivating enough for me to watch several episodes in one sitting. (eg. Noragami, KnB S1, Parasyte)
6 = A good show I had fun watching. I tuned in week after week with some anticipation. (eg. Zetsuen no Tempest, Kyoukai no Kanata)
5 = Average to mediocre (Reminder that 5.5 is actually the midpoint of a 1-10 scale). These were standard anime experiences and were decent. Many flaws but enough positives to keep me engaged. (eg. Tonari no Kaibutsu-kun, Blood Lad )
4 = Overall mediocre to bad. It had its highs but were counteracted by fundamental issues I had with them. I'd have rather not watched them but that knowledge only came in hindsight as there were good moments/episodes. (eg. Log Horizon S2, Tasogare Otome x Amnesia)
3 = I know what I dislike/hate so I avoid shows I know I will find bad but in some cases, shows start well and then nosedive completely. Overall a very bad show.
<3 = To get a 2 or 1, a show would have to offend me. These would be awarded to shows like Kiss x Sis, Yosuga no Sora, the infamous Boku no Pico etc, none of which I have watched, am watching or will ever watch.
I rate by enjoyment which is the ultimate factor and end result of watching a show. MAL and many of its users have this deluded view that enjoyment is somehow a factor rather than an end result. If a show elicits a positive reaction from you, regardless of the origin of that reaction, you'd be a liar to discredit it. For one's personal reactions to any artistic work is the only criterion which remains constant throughout time. Whereas artistic periods and the general consensus inevitably changes over time due to political, social or even economic realities, it is what your brain "feels" that stays the same. And I feel it is imperative that one should remain true to him or herself and make their own judgements free from others' judgements and opinions. Enjoyment is also a misused term in the MAL community. You enjoy something BECAUSE the plot was good, the characters were good etc. You cannot simply separate the two because plot, characters and any factor you as an individual care about when watching a show is a subset of enjoyment or to use a more fitting term - satisfaction. Everything contributes to enjoyment/satisfaction. It is the end result, not an independent constituent factor. I also find it foolish in most cases to have a normal distribution (Bell curve) of ratings because unless you watch every anime regardless of what it is, you should watch stuff which you like and by default, your average rating should be higher than a 5 which will naturally create a skewed distribution. There's no reward for masochistic and obsessive compulsions to complete shows. You're the only one that suffers, both from a bad experience and the opportunity cost of wasted time. So essentially, be honest with yourself.
