Iron Man 2 as well
Fun movie, got to the action much faster than 1 did. I'd equate it with Spider-Man 2. The hero was already established, so they got right to the meat of the story. Only complaint is that they replaced Terrence Howard (same thing pissed me off in The Dark Knight).
Iron Man 1: 8/10
Iron Man 2: 8.5/10
I'd probably give it a higher score once Captain America, Thor and The Avengers come out.
OH! And I spotted the Sega logo in the movie! Hint: Pepper and Tony make a toast.
