Betterman - idk if its because its old, but when i watch it i feel like i could be watching anything else. It didnt catch me and i dont identify with it.
Evangelion: 2.0 - Dont take me wrong I loved NGE i watched it countless times(more then 5), for many years what was said in that anime reflected directly in my head, but all the continuations\OVAs\whatever? didnt even tried to watch them if i didnt like the start, those ovas and stuff are only for the people who watch NGE for the fighting stuff, with sucks.
Gintama - comedy for the sake of comedy (wtf??), couldn't even pass eps 4 (out of 200).
Gosick - i love dark characters, i love goth themes, i like psychological anime. When i started watching at every scene\episode i would think "another goth\emo\whatever cliche".."and another"..."and another"... cliche cliche cliche... "i'm sick totally, what a freaking wanna be something anime".
Guilty Crown - didn't liked it much, actually ended up finishing watching for other reasons but was a bit waste of time.
Bleach - The first arc\season\whatever is good, till it saves Rukia, loved it, but after that, just some product for the masses and to make money.
Yondemasu yo, Azazel-san. (TV) - Cant even remember whatching it, just know that i dropped it at the first episode.
Naruto - Too much feelers, there was a time when it was good tho.
