I'm just getting bored of the whole film industries idea of a sequel. Which seems to around the idea that each one must be bigger, more explosions, more drama, etc.
Its not always bad, but they always seem to get a few good ideas, and then flog them like they're going out of fashion.
That and the fact that the iron man suites seem to now be made of paper and everyone and their dog can now break them, but its ok, because he designed it that way -.-
