I don't doubt people will continue to do so. Doesn't make it right (or wrong). Again haven't seen CA, I can't really speak to the quality of the film. I would have seen it, but...
I used to be a fairly regular movie goer. Lack of show-times I want to see and lack of willingness of theater owners to police the audience and throw out people who think they're in their living rooms has contributed to me seeing less and less films. CA had no show times that I was willing to risk an unpleasant experience of some goofball(s) talking at the screen, talking to each other, talking on their phone, talking to their kids, letting their kids run around the theater like it was field day at school, etc. In a way these issues are tied together.
Nominally I think it is true that there are more women than men in the US, but I think its in the upper age brackets. I think the younger age brackets are more even or slightly more male.
