I like the idea of a dark Batman movie that still has the surreal elements of the comics. I liked Nolan's more realistic take on the Batman franchise, but there were many things from the comics that just wouldn't have worked in his movies, and I think it would be pretty cool to see some of Batman's more unreal elements on the big screen next time around. Shake things up a bit, you know?

The Arkham Asylum/City games did a great job of mixing darkness/grittiness with the tones of the comics, and imo it would be pretty cool to see something like that on the big screen.

To me Rocksteady isn't as dark as Nolans and thats what I want. I also think taking the "realistic" tone out of it will help a ton, as you said.

I just don't want emo batman anymore, and more importantly I want him to focus on his detective skills more than his fighting skills (like Rocksteady and the cartoons do)
