I've been excited for this movie... well, ever since I saw Batman Begins. But especially since I learned that the Joker was going to be dark (more true to the comics) and played by Heath Ledger. I remember thinking at the time how perfect a casting that was, and everything I've seen since appears to back that up.
I also love that they flat out replaced with Katie Holmes as Rachel Dawes with Maggie Gyllenhaal. Holmes was awful, very distracting from an otherwise amazing movie.
Seems to me this movie will be breaking some records this weekend, too. Came across
this article a few days ago. It seems the pre-sale of tickets has been so intense that some movie theaters won't be closing for well over 48 hours to handle demand. The midnight showings tonight sold out so fast that they posted 3a showings... which were so popular that there are now 6a showings that lead right up to the 9a crowds. Even down here some theaters are going 12a, 3a and 6a and others have up to 12 screens starting between 12:01 and 12:30a.
