I do think there is a bit of deflation for the film due to the shooting, but I also know that in at least some cases there just wasn't as much demand to see TDKR during opening weekend. As an example, my close group of friends(six people including myself) have never planned to see this film on opening weekend and we're all comic geeks, most of us for over 30 years, that usually see the major Marvel and DC heroes on opening day. The trailers for the film just never showed us anything that gave us that urge to go out and contend with the crowds. We're not all a bunch of Nolan/DC haters either. Four of us, myself included, thought TDK was the best superhero movie ever made when we saw it. The other two thought it was the second best. We all loved BB and TDK, but the selection of Bane as a villain, the really lackluster trailers, the early reports from months ago about problems with the sound mix and other contributing factors convinced us to just wait a bit to see TDKR. I know that we can't be the only 6 people in the country that felt this way so I do believe that this film wasn't anticipated quite as much as some people seem to believe and the midnights do lend credit to that. We'll never know exactly what the movie could have made, but I never thought that records were on the table with this film just from the evidence I've seen from my friends.
