DC is using the whole "Japanimation" style in their movies, I personally hate it. The blood has increased a lot (a small cut releases an incredible amount of blood in seconds, damn japanese style) but is a minor problem. Oversexualization, poor dialogue, shitty acting (Alfred and Dick are the only good things in Son of Batman), etc.
DC is trying to get the whole anime fanbase but they do forget the normal fans. Seriously, if Assault on Arkham is shit (the acting is no more a point since we have Kevin Conroy and the animation style is a little better since it's inspired by Carlos D'anda artwork), I will drop DC animation.
