Lets get to it.

What initially intrigued me about the movie was the time-machine gizmo could only be used to view the past. This is new as most time-machine movies involve going back to the past to change things, which I find to be very annoying.

The movie would've been much better if thats all the time-machine could do. And even when it was established that you could interfere with the past, the movie explored the theme that you cannot change the past, which would've also been adequate, but we all know this is Hollywood. You must save the world, so they basically messed up what could've been a great movie.

And the terrorist guy seemed to also hint at the theme of not being able to change the past, but for some reason the story took the mediocre, uncreative, dull approach.

Very disappointing movie, its watchable, but I'm giving it a 1 because in the beginning it looked like it could be a classic, but degenerated into mediocrity, so I think thats a tragedy.

Don't watch this movie.
