I hated that scene. I never could figure out why Gordon had the symbol on in the first place. He didn't know Wayne manner was getting ran sacked. Then when he sees the Riddler messing with the Bat signal he freaks out, Batman eventually shows up bursts through the clouds. And Gordon yells, "Go hit him!!!"
Ok so why did you put the signal on in the first place because it obviously was for the Riddler, that came after, and obviously no one else was in trouble...so I'm convinced this scene sucks.
Also the that bat flying at the camera in the flashbacks is actually still that giant bat if you look closely, it was suppose to fly up to adult bruce and confront him, they just cut it before it got too close.
