I keep hearing about District 9. I should probably make sure to see it at some point. I'm not really even sure what it is about. Don't worry about telling me though, I tend to enjoy movies much more when I have no idea what they are about before seeing them.
As far as TV shows go, Journeyman was actually quite good. Its sort of a Quantum Leap rip off except that the main character (Dan) is unpredictably shifted, physically, back and forth between his own time and some other time. The basic idea is the same though, he travels to other points in time to change small events and improve people's lives. A significant portion of the show deals with how this effects his family life, having as wife and kid, and how he tries to prove it or hide it from different people in his life some of which think he is drinking or doing drugs (lost time, not showing up when he is supposed to, telling strange stories). The writing and dialog are pretty clever in my opinion. One of the neat signatures of the show was that when ever Dan showed up in some other time there would be a radio nearby playing a song that came out that same year.
