Well, another Hugo-nominated film based on a comic that I had barely heard of. I found the politics stupid to the point of being offensive: I don't think anyone with the slightest notion about Afghanistan could find either the kidnapping plot or the Iron-Man-rescues-the-villagers scene anything other than crude and simplistic. (And bloke who's grown up living off the fortunes of his dad's arms business is converted to Doing Good when he suddenly realises that the bangy things kill people? Gimme a break.)
The effects were pretty impressive, but essentially allowed Iron Man and Iron Monger to ignore the laws of physics to the point where there wasn't much tension left. This will not be at the top of my Hugo ballot.
