For THE CANON (an exceptional standard of the medium), I chose BLUE VELVET. However, I do think ERASERHEAD is pure nightmare cinema that probably sticks with you in a way that BLUE VELVET doesn't. It is creepy, cryptic and haunting. But without BLUE VELVET we don't get the popular definition of something being "Lynchian". BLUE VELVET is a part of the collective consciousness in a way that ERASERHEAD could never be. Since this is a versus episode, BLUE VELVET makes sense as the clear choice. They are both great movies, though in radically different ways.
