I am deeply hurting from what that guy said, but I don't think he paid attention to the film, because he didn't even know somethings, that was obviously said in the film. Like why Whiplash attacks Tony Stark.
But you can't watch a movie one time, and expect to have a final thought. When I first saw Iron Man, I literally said I hated this movie, because I didn't appreciate and pay attention to the overall concept. But now matured, I realize how much of a masterpeice it is.
But even though I haven't seen the film, there is a lot going on.
