Great watch, will likely watch again, and do recommend.
While I wouldn't normally consider clairvoyance "time travel", the way it is implemented in this movie is essentially time shifting. He "thinks" himself forward in time, and then essentially time shifts himself backwards to a time before he witnesses the consequence.
It's such an interesting concept, but potentially un-cinematic. They honestly do an amazing job of displaying Nicholas Cage standing in place to "see" and making it seem interesting.
Juliane Moore helps by being a badass lady in charge, but Jessica Biel (a proven entity herself) just doesn't have the opportunity to be little more than a damsel. Cage carries most of the movie, but is a lot less "crazy" than he is in other movies, if that is any comfort.
Definitely check this out next time you're looking for an "out of the box" action flick.
I don't really know how to put the thought that came to me while watching _Next_ in a way that makes any actual sense, so I'm just gonna out myself as kind of an idiot and tell you all what that thought literally was: "I'd like to see this movie in a different movie".
_Final rating:★★ - Had some things that appeal to me, but a poor finished product._
