This is another one of those first camera high concept movies. I was excited about this one and all in all it was a decent watch. They did a good job of portraying the time travel with minimal amount of special effects. The characters played very well off each other and the story developed well. The only knocks I could make on this are that it took too long to really get going with the time traveling and that it become a little too centric on a teenager being in love. The movie was much bigger than that all along but shrunk itself down to be focused on that.
I would somewhat recommend this movie. It's a decent watch of a great premise but definitely could have been so much better.
