@micah: it just doesn't feel right. it's an american movie. it's really close to those awful marvel animes.
I liked it in Flashpoint and Assault on Arkham, but your right I don't want it to be the default style for all of them. And hey the Marvel Animes were pretty good. I enjoyed the Blade, Iron Man, and X-Men ones. They genuinely were legit animes.
Arkham doesn't look like these though. I would say everything since Flashpoint not including arkham have a similar look that I don't find very appealing.
