At one point, the writer in me kicked in and said, "If he doesn't start the main plot sequence in the next 5 minutes, this movie is going to suck wind."

I'm probably going to be the only person ever to say this, but this is exactly how I felt halfway through Iron Man. And that did taint the whole movie for me. I know everyone else looooved it, but...

(And having a bit of an interest in neural interfaces for prosthetics, I've wondered about that last issue, even though I haven't seen it yet)
