My wife and I gave Iron Man 4 stars only because we have to reserve 5 starts for truly perfect movies. That said, within the comic book genre, they don't get any better than this. Funny, thrilling, great effects, great acting - it has it all. Downey is great, and you get the sense that it's him even when all you see is the suit. Bridges is convincing, Paltrow is lovely, Howard is a great friend. Even the robots are entertaining.
