Yeah, I'll definitely be checking this out.
Another movie that strangely reminds me of TSA is Valhalla Rising (also one of my favorite movies ever). Very dark, brooding, mysterious, with a strange mysticality to it that's brimming just beneath the surface. It's extremely light on dialogue and to some extent, plot, however, and the middle drags a bit, but the first half hour to forty five minutes is one of my favorite sequences in cinema.
Also Mads Mikkelson plays Odin, so yeah. Badass.
