I quite liked the movie, which honestly surprised me! I had written off the Iron Man movies with number 2, but this one really did a lot of good. Establishing that Tony's essentially a gadget character was probably the best decision they made. Spoiler I'm not sure how I feel about the portrayal of Extremis, though, and I'm a little disappointed Tony doesn't pull the whole nanotech thing like he does in the comics, but overall they did a great job. I feel like staying truer to Extremis from the comics could've worked just as well as what they did, thematically. Ben Kingsley is clearly having a hefty helping of ham and cheese, and it works. Harley, who I thought I'd dislike, wound up being the best kid sidekick since Short Round, and that's saying something.
