Elfen Lied (TV)
Some say that it's beautiful and philosophical. I say that it's gory and dumb. The history is told by a total illogical and emotional point. It tells that humans are evil because they hurt each other but don't explain why the other animals are not evil when they do so. It's very sec. XIXish, because, in the end, love brings redemption to the protagonists (it doesn't matter if there is evil since there is love). Lame.
Fullmetal Alchemist (TV)
Higurashi no Naku Koroni Kai (TV)
A classic example of how the censorship can destroy an anime. The first season was indeed a masterpiece, because it was one of the best HORROR THRILLER animes ever. But, this season is just romantic crap. There is no paranoid Keichii, nor delusional Shion... Just some retard kids telling the world how good is the power of friendship.
