I hate most anime.. there are very few out there that I like.. they all seem same same now, like there are no more plots to do.
I can't deside the one I hate the most, so I'll go with the type I hate the most:
Main character = Guy. Guy gets a gaggle of girls fall for him. Guy is to stupid/lame to pick even one girl to date/love. Girls all seem to have the same personality as other girls from animes similar to this setting.
