I’m fascinated with time travel movies, and try to watch all of them.  About Time (Blu-ray release 2014-2-3) sets up unusual rules for time travel purely as a plot device.  The first half of the movie is basically about getting a girlfriend aided by time travel.  The second half is more about life.  If we accept its strange rules about time travel, and more importantly the dishonesty in marriage, I think this is a charming movie to watch (with almost no tragic scenes, unlike the Butterfly Effect series (2004, 2006, 2009)), with a positive message about life at the end.
