I'll probably just wait for IM3 to come out on Blu ray, but I'll definitely be seeing it. I was never much of a fan of Robert, and when he Charlie Sheened himself I was thinking good riddance, but when he came back to acting he was great. I really enjoyed the Sherlock movies and the Iron Man/Avengers ones. He's really brought himself back, bigger and badder than ever. I don't think they could have chosen a better actor for the Tony Stark part because it's almost a biography for him. Beginning of IM he's almost dead, and each time he gets a new suit he gets better and better.
It's the same with Leonardo DiCaprio. After Titanic I couldn't stand to watch any movie with him in it because he was always the tool from the ship but when Shutter Island came out I was surprised how good an actor he had become. And he proved it again in Inception and J Edgar.
