Last night I watched a movie that either came out in 2009 or 2010 called
Moon. It's directed by David Bowie's son, Duncan Jones. It was an awesome Psychological SciFi Thriller. You can stream it as an instant-play on Netflix if you're interested. It's one of the most unique SciFi stories I have seen in a long time. It felt kind of like The Cube meets 2001: A Space Odyssey. It's best if you don't know what it is about though. All of the suspense is about trying to figure out what is really going on.
Otherwise, my favorite movies have been similar to others here: Scott Pilgrim, Inception, 127 Hours. I've been meaning to see Black Swan, but haven't yet. The new Harry Potter was also an interesting though morose detour for the series.
