This is one of those movies that you know is going to be awesome going into it, and you leave the theater thinking how awesome it just was. It's just one of those well spent $10 adventures ($20 if you have a girlfriend, and zero if you're lucky)
You get hooked into the movie in the first 20 seconds, and then two and half hours later you breathe. Heath Ledger's performance in this movie is on the verge of scary. I've never seen crazy so up close and personal-- he became the joker.
Right when you think the movie is over, it'll hit you in the face and pick back up again. The plot has so much substance, if you're like me, you'll get a few character surprises that you didn't expect.
It would have been nice to see more of Bruce Wayne. His few comedic lines are on the verge of perfection. Two of which I hope I can use one day-- haha. It was feeling like a long movie, but I really don't think I would change a frame.
