The Sacrifice
Visually stunning and basically as close to a circle as a movie can get, Sacrifice is a trip into the virtue of letting go and the meaning of a regretful existence by showcasing people who all react differently in the face of Death. You get the sense of a supernatural presence throughout and are constantly worried about the state of being of everyone offscreen. I don't think I understood half of it, but then again with this, it doesn't really matter.
