Rarely, very rarely, does a studio make a great film based on a comic book or a video game. Well, this time, they succeeded! Iron man is a kick ass film. I thoroughly enjoyed it.
1) In movies like these, you have to suspend reality for a couple of hours. True, someone falling from the sky like that should have died, but what about
a) building an exo skeleton from parts of a missile and metal is unbelievable
b) they were being watched by the terrorists around the clock which any right-minded wacko would realize that they weren't even building a missile. Kinda obvious
c) That stark could perfect flight in a couple of days. Where is the power source?

d) that the bad guys could reverse engineer the Ironman Suit in 3 days and make a working copy of it
e) that the government couldn't have done the same damn thing
f) that stan lee in his cameo appearance had 2 beautiful women around him (he should have had 6)
g) that all throughout the film, I was thinking to myself: "Damn, this guy is a dead ringer for young Al Pacino"
They could make another godfather film using him.
But seriously, when you go to the movies, you have to suspend reality for a couple of hours, relax, and enjoy the movie!
