Frontier(s) (2007, Xavier Gens.) - 108 min.
I had heard good things about this one when it came out, and I finally got around to seeing it. This film was absolutely beautiful. It had that gritty, yet sort of surreal look that French horror films have displayed lately. The characters were all pretty intelligent (i.e. I wasn't yelling at them for making idiotic decisions) and the bad guys were pretty scary. I think Frontier(s) is my new favorite French horror film of the past couple of years.
