Topic: A fairly unique story
For those with Netflix, check out a movie called Jonathan. Although I've seen stories about multiple personalities, Jonathan is a sci-fi spin on that. It's about two personalities (Jonathan, an uptight nerd, and John, the rebel) who each get to live 12 hours at a time, then their personalities switch thanks to an implant created by their doctor/adoptive mother. The film shows their structured lives and how they communicate with each other, and then there's this girl, and the threads completely unravel. I've seen it three times. I find it spellbinding.
