About The Dark Knight movie?

The reason everybody is raving about it, besides Heath Ledger's brilliant performance, is because it's darker than any other Batman movie. It's not comic-booky with cheesy over-the-top acting and it is also an action movie which most people like - it has awesome but realistic stunts. Also people are beginning to think that Christian Bale is the best Batman of all time- superior even to Michael Keaton.
