Have wanted to see this movie since I saw the first trailer, and it was better than I hoped. Engaging, textured story and characters, a showcase for how good Downey, Jr. can be. Doesn't take itself too seriously, and could be a great franchise for those of us who want substance in our plots. A movie for those who value actors, writers and camera work over computer programmers - there are some excellent special effects, but they do not take over the film.
