Starts out with enough Intrigue and mystery to keep you engaged until about one-third of the way in you realize that this is just another run-of-the-mill time travel movie where somebody figures out that there are some bad Shenanigans going on, needs to stop it, by traveling through time, figures out how to do it, and then basically destroys the either past or future or both timelines. End of story. Consider yourself having seen the movie. You're welcome. If you're morbidly curious enough to go ahead and see it, at least you will only waste 1 and 1/2 hours of your life versus 3 hours I've wasted on some other equally unworthy films.
