To add to what some other reviewers have been saying, Robert Downey Jr. IS this movie. Without him it's another bland "action packed" superhero bore-fest. He makes it hilarious, and mostly because the movie doesn't take itself too seriously, it works on so many levels. The special effects are very good, but the main draw is the characters, as it should be. While this won't end up being the best blockbuster this summer, with such a huge lineup, it will probably be one of the moere memorable ones for me.
