Can I be honest? I just don't care for super heroes. I have a terrible time suspending my disbelief when it comes to capes and super powers. I dislike super hero movies because I think they're cheesy.
That being said, I'll watch Batman Begins or The Dark Knight time and again. I thought Robert Downey, Jr., was brilliant in Ironman (1 and 2). Make a good superhero movie, and I just might watch it.
