He can build a machine to spy on all of Gotham, abscond with an entire ballet troup, fly in and out of skyscrapers with unbelieveable precision. So, why can't he get Morgan Freeman to design him a voice disguise box so he doesn't have to talk like a creepy old man with laryngitis?
Other than that, this movie was fantastically assembled. The joker has you terrified, then laughing, then terrified again. But, if you are squeamish... don't look at Harvey Dent. That god awful cleft chin is enough to make you put down the popcorn. His appearance improves a little near the end of the movie.
I will see this again and again. I bet it's sweet in IMAX!
