OK, we’re going to overlook the creepiness of Marty McFly’s mom having a crush on him and enjoy the overall goodness of “Back to the Future.” It’s a simple boy-meets-girl story thrown in a blender with a complicated time-travel plot that explores the cultural differences between the 1950s and 1980s. This movie came out in 1985, thus a Huey Lewis and the News song leads the dated soundtrack, but the story holds up well even when the costumes don’t. Michael J. Fox was 25 when the movie came out but he plays a skateboard-inventing 16-year-old that looks like he’s 13.
