I was a big fan of the Iron Man comic book series. This movie didn't come close to what Iron Man was about. Rather than have a real plot, with characters that you can care about, this new movie relies on made-up technological displays and lots and lots of explosions. No real substance. As far as having Scarlett Johanson being as an action heroine - not really believable! Still great to look at though - blonde or brunette. What was Gwyneth Paltrow even given credit for being in the movie...I'll bet she was in it for all of twelve minutes. All-in-all, at best this is a rental and not worth the money I paid for admission.
