Iron Man was everything I had hoped it would be and more.
A more coherent discussion of it will have to wait until I have a disc of the movie in hand, but
a) go see it now; it works beautifully on a big screen
b) Robert Downey, Jr., is only one part of a wonderfully-composed cast (Jeff Bridges and Gwyneth Paltrow rounded out the chemistry)
c) the special effects, as spectacular as they are, are never less than completely convincing, which is really saying something these days.
As I told my friends, "I still can't find my butt. I think it was blown through the back wall of the theater."
