Fun movie written by screenwriter who flunked physics

Rating: 7/10 (10 April 2011)

I give this movie a seven because I must admit it kept my attention and was well acted/edited. However, although I realize this is just escapist lore, I think the "science" behind the time loop could have been better explained. One thing I noticed that, although he is cascading from one parallel universe to another, with each one being slightly different, the identity of the villain never changes. Also, how does the controller know that the returning controllee is the same entity that originally went on the mission? Nevertheless, as pure entertainment, and if one allows oneself to release everything learned in Physics 101, it's worth seeing.
