There are some major differences between The Dark Knight and Begins. Firstly, the music is extremely disconcerted compared with the 'majestic but unfinished' tones of Begins - but it suits the film's tone: Anarchy in every sense. There was a more solid singular villain (compared with the many in Begins) - but there was also a lot more henchmen in TDK. The martial art direction was faster and more efficient - as mentioned in the film, learning through experience.

I was disappointed at the role of Scarecrow in this film, it just felt like a loose thread and wasn't quite closed up or explained, and the ending, while it wasn't what I expected (others have said that it was predictable, but for me it wasn't) was solid and suited the film well.

All in all, this is a film that is quite close, if it isn't already, a masterpiece. Nolan has a great thing going and unlike previous 'Superhero' adaptations (Spiderman and Fantastic Four for example), there isn't campiness creeping in. In face, if Batman Begins was 10/10, The Dark Knight deserves a 12. Quite simply, the best possible sequel that could've been given.
