This is a film that happens to have Batman in it, rather than feeling like a Batman film. That's not a negative, as here we are more pared down and real world than in the Nolan trilogy, with a Batman much more integrated (whilst not always accepted) with those serving the law.
The voiceover and accompanying visuals are reminiscent of Rorschach's mumblings in The Watchmen, the dark and brooding Gotham (is it ever any other way) is beautifully shot. It's been stated elsewhere and I agree, there really is a heavy Se7en influence to the visual aesthetic.
Pattinson is hard to judge as Bruce Wayne, so little is he in that role, but he plays an aloof troubled Batman well. All the characters are well drawn and acted, with particular kudos to Paul Dano as Riddler.
Perhaps the relationship between Batman and Selina Kyle feels a little rushed in a film that takes its time. Bouts of action are fewer and far between than in past Batman films, and there's a sense that the final section of the film might have been put there to redress that balance.
Overall, this is a thoughtfully paced, well acted film that keeps you interested, with a grim palette that keeps things feeling ominous. A great score helps too. It's Batman, but not how we know it.
