Review Detail

At the core of it, this edit is an improvement over the theatrical cut. The few deleted scenes that were reinserted are really nice character moments, which is something that Iron Man 2 has always had going for it.
At the time of it's release, the biggest criticisms of IM2 were that it was doing too much "set up" and not focused on telling a compelling story in it's own right. That problem is almost entirely solved by adjusting the focus to Tony and his heart condition.
The best edit is probably the decision to make Tony riding in the F1 race something that was planned. Because as Lapis sated, how would Vanko have known to attack him on the track if it was a last minute change? Flawlessly filled in that plot hole!

The only reason I don't rate my enjoyment higher is because I personally love Sam Rockwell's Justin Hammer, and I'm disappointed to see him cut down so much. Again, it's a movie with a lot of character moments, and I think he deserves to have a few more.
