Saw Iron Man 3 This weekend. I couldn't see Tony Stark played by any other actor than Robert Downey Jr. Amazing performance by Ben Kingsley as well. He almost stole the show.
Finally, he kicked butt when the Aliens invaded, but his suit seems to fall apart amazingly easily in this film. I'm thinking that this is a reference to Tony Stark's state of mind, but maybe I'm giving too much credit. Overall, it's worth a trip. You will be entertained, and it's actually safe for the kids to watch.
