Just saw the movie today. I loved it.
I thought one of the most clever, most ".....WHAT!??" moments was the part where Pepper is downloading the files from Stark's computer, and she's translating the original hostage video, and it's way different than what I thought from watching the actual hostage scene in the beginning.
Very well acted. I went into it knowing absolutely zero about Iron Man and still enjoyed the heck out of it. Lots of seat-grabbing, oh-snap moments.
Oh, and the part where Stark takes his suit and chases down the double agent in the giant suit, and Rhodes turns and looks at the spare suit in the workshop, and I was all "OH NO HE DIDN'T" and he says "next time" and I was all "ROFL"
