Not read the comics, but I have only watched the animated series and feature films. In the latter, or atleast most of it bar a couple of exceptions, Batman's persona is close to Nolan's films. Pretty dark and brooding, and his costume is said to mirror his pain.
Everyone wrote Heath Ledger off, so I am not going to make the same mistake with Robert Pattinson. Let's see what he looks like once he is in the batsuit before jumping on his looks and calling him a miscast. Atleast they got the Joker right in all probability with Joaquin Phoenix in the standalone movie, though its' pretty sad Leto will continue to portray the character in other movies.
