This movie was solid. Robert Downey, Jr. did better than my expectations were. Terrance Howard was a solid addition to the cast as Jim Rhodes and I would definitely expect him playing War Machine in the sequel due out in 2010. Gwyneth Paltrow did a great job playing Pepper Potts. Jeff Bridges shaved his hair in order to be cast as Obadiah Stane, also known as Iron Monger.
But the best part is the scene that is after the credits. I won't spoil it.
