Wow. I never thought about the tracking device. Great point.
I walked out of the film thinking the ending was genius. Am I the only one who thinks that Bruce really did die, and that Alfred was having a lucid dream of Bruce and Catwoman at the cafe. I mean the scene was nearly identical to Alfred's dream at the start of the film.
Anyway I freaking LOVED the movie. It's my favorite of the entire trilogy. I can't believe Nolan actually went with Bane breaking Bruce's back. Amazing. And Anne Hathaway totally changed my view on Catwoman....what a great character.
