Mmm, I agree AnneFan. We didn't see much of "broody" Bruce in the first two films because of how focused and determined he was, which I liked. But seeing the depressed, brooding and lonely Bruce completed the character in a way.
It's like the scene in Batman Returns where Keaton is sitting idly in the library just waiting for the signal to come on. Imagine Bruce being in that kind of state for 8 years, and the signal never turns on once
