I went to see this movie a couple of weeks ago expecting a decent movie. However, after I came out of the theater I was shocked at the level of dedication needed to play the Joker. Joaquin Phoenix had to lose a ton of weight until he was basically skin and bone and play a convincing slide into insanity. His acting is so amazing that you forget that you are even watching a movie at all, and it is so mesmerizing to watch his new take on the Joker. This movie was engaging all the way through and had a perfect ending to match. What a fantastic movie.
