I saw Captain America in the theatre this week with my older son. It was a good movie. The theatre was around half full on a Thursday night. Which is about how I like it, I prefer to see movies when they've been in for a while.
I noticed a few movies this summer. I missed Bad Teacher but that was kind of a borderline DVD anyway. Horrible Boss looks good plus Planet of the Apes and Conan all look worth seeing there.
I don't go to the theatre a lot. Before this week I think it was Star Trek and then 2012 before that.
