I personally thought because I didn't see the previous movie and I was more into seeing Hancock than the Dark Knight. But I end up seeing the Dark Knight instead of Hancock, which I could avoid if I had spoken up in time to my father that I want to see that movie. Oh, well. At least, going to AMC to see movies like that is free for my family, considering my father has work part-time there for years; so chances are I could see Hancock, if it is still in theaters, the next time that he need to be called in.
Anyway, not that I want to repeated what many others here have said, but I thought that actor, Heath Ledger, did a very good job as the Joker of the film and it is very sad that this was his last film before his death. I personally thought the Batman in this movie wasn't really the main focus in it, rather it more like the Joker was as he stole the spotlight throughout the movie. I like pretty much every scene that the Joker was in and I found the ending of the movie to be alright.
That's really all that I thought of it. Just thought that I should let you all know. By the way, happy belated birthday, Bzpower.
