The only thing I can think of that anime and manga did right was Death Note and anything by Studio Ghibli. All the rest is overhyped, overpowered, stare contest, OMG LAZZZORZZZZ!!!, angsty hero involving, killing half of the already unnecessarily big cast, and ridiculous world destroying plots.
Translation: DBZ, Bleach, Naruto, and anything else that plays out like them is terrible.
With that being said, I only like Miyazaki films and Death Note. Death Note for being more of a comic book than an anime and Miyazaki for actually using creativity and imagination.
