I thought it was pretty great. I didn't see it coming, that's for sure. Iron Man's villains have never really been silver-age-y, so the idea of this over the top, flamboyant villain didn't really fit. To have it all be a ruse was good, and the actual villain was interesting, if not very original. I also had a huge smile on my face when ALL of the Iron man suits showed up. And Pepper being the one to actually finish off the bad guy? Nice.
The part of the movie I liked the most though was the shrapnel finally being removed. From shortly after he got it up until now, the shrapnel hasn't meant much. It was just some plot device to justify having the generator in his chest. Now though, it comes to light that it was Tony's "hair shirt" [http://en.wikipedia.org/wiki/Hair_shirt] the whole time. He could have had it removed as soon as he got back to America, but he deliberately kept it there as a reminder to be a better person and not forget the lives his weapons have ruined. At the end of this movie, he finally had them removed, meaning he realized he no longer needed his "hair shirt" because he had truly become a better person (hence his "cocoon and butterfly" metaphor). That was my biggest takeaway from the whole film, and it was a really fantastic ending to the Iron Man series.
Also, the stinger that shows he was narrating the whole thing to Bruce Banner? Nice. Hopefully might mean more Hulk movies with Mark Ruffalo in the future, even though the current line-up doesn't show any.
