popotan (nothing happens, shit story)
nagasarete airantou (nothing happens, shit story)
rosario+vampire (ONLY fanservice happens, main character has no personality, shit story)
shuffle (shit story, bogus characters (except kaede), main character is a stupid douche)
ergo proxy (what is this i don't even. couldn't understand anything that happened without careful rewatching and revision. crap story/characters anyway)
zero no tsukaima (FUCK I HATE LOUISE GODDAMIT SHE KILLED THE ANIME)
toradora (taiga is a fucking retard. minori is better)
school days (makoto. is. a. DICK. seriously, i almost died watching him fuck up everyone's lives, and i actually laughed when he had his ass handed to him by sekai (who is the best character imo) in the end. worst anime ever. very unsatisfying. i had to wash the taste of it out of my brain with ga-rei: zero)
terrible, the lot of them. there's probably some more, but these are the ones that have left lasting scars on my brain
