Unstoppable is a waste of time. I nearly fell asleep in the theatre. It’s an insult to half decent popcorn action flicks like Salt. Rent “Speed” instead. That’s about a bus that’s out of control instead of a train, but it also has plenty of other explosive action scenes and it’s silly enough to enjoy and not take seriously. I’m not sure if “Unstoppable” has any action scenes. It has some fast editing, but quick cuts and jerky camera moves can’t make up for a lack action. Skip it. Don’t even rent it.
