The first Iron Man movie was great. The second, at the very least, was good. This was the kind of film where the screenwriters (or someone in the development process) felt the need to give the hero a cute kid as a sidekick.
Are you beginning to get that sinking feeling?
I can summarize this film quite easily. And I think I can do so without giving away anything that could reasonably be considered a spoiler:
Hero starts off superficially on top of the world after previous triumphs. Yet not without inner demons gnawing upon his soul (c'mon people - this is Tony Stark). So he gets into some real trouble and has to go away and find himself. Then, in the end, we have a climactic final battle. Oh yeah, and there's an evil conspiracy that needs to be uncovered.
Speaking of which, this movie did have a political subtext relating to events in the real world. But not the kind of subtext you get to feel clever for having deciphered. More the kind that leaves you with an aching skull after having been hit over the head so hard.
Finally - and I realize not everyone will consider this a fair criticism of a movie based on a comic book - there was absolutely no sense at all in why the baddies' superpowers worked the way they did. None. There's a spare slot in the human brain/genetic code, so therefore... well, you'll get to see. I can't help but wonder if this was all conceived as nothing more than a series of cool special effects.
Robert Downey Jr.'s rendering of Tony Stark is as good as it ever was. But the point is, for it to be worth making that third movie, there needs to be _more_. And in this case, there just wasn't.
I watched this movie at home. About 15 minutes before the end, just as the climactic final battle was getting underway, I was feeling pretty sleepy. So I went to sleep. I finished off the film the next day, but only because I'd already decided I wanted to review it on Amazon.
