It was a fun idea, but waaaay toooo long.

It's a good action/sci-fi movie. Some of the dialogue/slow scenes feel a bit unnecessary, but I enjoyed it. I appreciate the ending.

Although certain aspects didn't make logical sense, the movie was entertaining enough.

Convuluted. They didn't have older people go back in time so they couldn't see themselves, and only had people go forward in time who would already be dead (even though there were only 500,000 people left by the end, so not much chance of someone meeting themselves), and yet they go and change time anyway. The whole time travel paradox about being able to change time or not would just break down here. Not horrible, but not a great movie either. Glad free and part of prime instead of paying in a movie theater (which I won't visit now anyway).
