Where Iron Man 2 felt like a fumble on a perfect pass, Iron Man 3 feels like a success against the odds. True, it isn't perfect - anyone who accuses it of sagging in the middle will be hard to refute (par for the course on modern blockbusters)...But most of the time, it's great. Much better than Iron Man 2. Quite probably better than Iron Man 1. It's a triumphant return to form for the franchise.
