Quick, while it's still in theaters! If you like superhero movies, or if, like me, you like the idea of the superhero movie, but in the past have found actual superhero movies to be at least a little disappointing, and if you have not done so already, GO FORTH AND WATCH IRON MAN!
Iron Man avoids pretty much all of the superhero movie pitfalls I'm aware of. The story is neither overly elaborate nor overly simplistic. It doesn't take itself too seriously (as I suspect is the case with The Incredible Hulk, though I haven't seen it), but neither does it degenerate into tasteless camp (a vice which Transformers narrowly avoided).
The acting is good and the characters are fun--the only exception being the Afghani terrorists, who come off flat and one-dimensional. The special effects are well utilized. The humor is witty. The platonic romance is refreshingly atypical. The hero's character defects and weaknesses make his attempts at "do gooding" both sympathetic and amusing.
Very few of my favorite movies can be found in the "Action/Adventure" section of the video store. In fact, this may be the first one. Iron Man for Best Picture!
