Bad animes?
Blame! was probably one of the wrost... i don't know how the manga is but the anime is purly just a pieace of wasty shit...
Firestorm also was highly stupid, G.I.joe with a cool name and killer animation.
Wrath of the Ninja was annoying, espically in the end.

and that's about it, without considering commercial animes such as Baybladez...
