Like most sci-fi geeks, my anticipation for this movie had been building for a year. Like most sci-fi geeks, I was not disappointed.
This movie had everything a good movie should have: a great story, great acting, great action and a reason for the viewer to willfully suspend their disbelief. Iron Man has all of that. Yes, it takes some time for the fun to begin, but that time is used wisely, setting up our hero as an allegory for America: brilliant, untraditional, hard working, rich and distributing weapons of mass destruction to anyone with money. But Downey uses his acting skills to make Tony Stark a likable character, someone the guys want to be and someone the girls want to be with.
The mechanics of his transformation into a more compassionate, enlightened American is believable again because of Downey's outstanding acting talents. Having been duped by those in control, he quickly takes steps to compile a response, and THAT'S when the fun begins.
The entire concept of his armor and the CGI that creates it is just fantastic. The R&D sequences are some of the best moments of the film, topped only by him going into combat with the final product. My only problem with the film was that it seemed too short. They could have gotten away with another half hour of him kicking butt in the armor.
The rest of the cast support and build on Downey's talents. Paltrow is at her best, the highly efficient, loyal friend to Stark. Bridges (despite the fact he will always be The Dude to me) pulls off a believable, even likable bad guy.
What it comes down to is that I can't wait for the next one. Hopefully they'll spend more time with Stark in his armor next time. And they've already alluded to the whole War Machine subplot, so I assume they've got at least a couple of sequels planned.
