Saw it last night. Good stuff. Really makes ya think. If you had a hard time with Matrix, have fun with this one, lol.
It won the Sundance Grand Jury Award and the Alfred P. Sloan award, so ya, its quality. The movie is only 78 minutes, but it feels much longer, in a good way. This movie was made on a budget of $7,000, which is amazing. I got a kick out of the movie because its all filmed in Dallas, so I recognized just about every area they filmed in. They also filmed a few scenes at my university (UT Dallas), which I thought was pretty cool.
