It was decent to watch once but not something I think I would watch again. Decent story, but predictable and kind of ignores the fact that killing people in the past would change the future in unpredictable ways. Overall it was good and entertaining if a bit slow.

Great sci-fi action movie. Not complex. Fun story arc. A little predictable.

There were good parts and plenty of action but it was pretty much hokey.

Pretty improbable, but the family interaction kept it interesting.
