Big errors in this movie
I know the time travel issue has been posted before, but that's not the movie's only big problem. There are a few big problems this movie has that makes it hard to believe:
- When Van Damme goes back to his own time, he should be in a different universe, since he changed things.
- The time travel cart (which the police officers sit in when they travel back in time) disappears when they go back in time and then re-appears when they come back to their own time. Why does the time travel cart disappear, and where does it go?
- The whole theory of "the same matter can't occupy the same space at the same time" and how that affected the movie doesn't make sense at all. For one, your body won't have the same matter 10 years from now because the body's cells are continually replaced as they die. Second, if you touch your younger self, the matter isn't really in the same space; you're simply placing part of your body right up next to your younger self, which is different from actually occupying the same space. And I actually don't see why it would be a problem if you were to go back in time and make physical contact with your younger self. It seems like they made that up to add an extra twist to the movie (perhaps as a fancy scientific way to kill Aaron McComb).
I don't think Van Damme's macho-man demeanor (i.e., shattering that guy's frozen arm before killing him) and one-liners really helped either.
Having said that, though, I still think this movie's premise, story, and special effects were pretty cool.
