The way Iron Man 3 is structured as a movie, you can't exactly step in and say "this would fix the ending and thus fix the entire movie." But this edition of "How It Should Have Ended" does poke fun at a couple of the most obvious issues with the film. Spoilers ahead if you haven't seen the movie... oh wait its past the billion dollar mark I think we're all okay. In fact, stop seeing it and go see Star Trek Into Darkness. http://www.youtube.com/watch?v=OUYW0JyzydA
