So what's the worst anime you've ever seen or been the most disappointed in?

I really could't tell you what my personal 'worst' was, because those are usually the generic series that I pick up, watch for 5 minutes, see every formulaic trope in the book, and delete. +1 to whomever said Asura Cryin', because that's the one I last remember picking up and thoroughly being disgusted with it. If we're talking "So Bad It's Good", then it's definitely either Genocyber or Gundoh Musashi. 10/10 classics.

My personal worst was Tokyo Mew Mew. I went in with very high expectations for this one considering my cat girl fetish , but I could not watch more than 2 episode before I had to stop. Usually I always end up watching at least 3 episodes of every new anime before I decide to drop it or keep watching it, but this one was just plain bad.

I agree, school days.. it was like all light hearted one of those shows you just think snooze, then you get to the end SPOILER and she chops his head off and your like WTF THAT IS SO OUT OF nowhere! I mean what the hell?!

Honestly? ive been let down by the plot of several anime so many times i cant just list one. I got accustomed to anime/manga/visual novels as literature because of Type Moon and Urobuchi Gen. The bar was set pretty high, so im dissapointed by a lot of japanese media. I blame it on studios and publishers pandering to the likes of the current biggest spending demographic in japan and japan only: Male Type B Otaku. The biggest part of this is that Type B's in japan really dislike anything too complex and their attention wont hold if there isnt something visually appealing. This is the reason you get seemingly unnecessary things thrown into good stories. Its the reason why many potentially good books and visual novels always have some cute girl in some ecchi situation. (and the reverse for all fujoshi audiences) Its why Madoka Magica was packaged as a Moe anime, not because they wanted to but because they had to. Ugh.
