I highly doubt that, given now their biggest successes did not feature Robin. WB aren't dull enough to move away from a method that has worked well for them, that's why Man Of Steel looks like Superman Begins based on that teaser alone. I think this will certainly hurt a little at the box office this weekend just because people love to be paranoid, but reviews are positive in the majority and there's still home media sales for Christmas around the corner, as well as the inevitable trilogy box set.
No one stopped going to school after Columbine, no one stops going into banks because of gun-point bank robberies so why should people stop going to movie theaters? It's just ridiculous in and of itself that people associate this movie as the reason they may or may not be shot because of this madman's tirade. During the subway attacks in Europe, I didn't freak out anytime I stepped into one. It's a rare occurrence.
