It's easy when you have a good story or a credible cast of actors. When you've got almost everything going for you, it becomes difficult to pinpoint where the director should be praised and where his cast and crew are more deserving. In this case, everybody deserves tons of praise. The DVD itself is as top-notch as the film. The anamorphic video is impeccable.
Grain is completely absent.
Artifacting is not an issue. Black levels are very good. The only complaint to be had here, is that there is a hint of color oversaturation. However, if you notice a sort of overly bright daylight, don't tweak your video settings. The director purposely overexposed some shots to a degree, in order to flush out the light.
