Not sure exactly how to phrase my feelings about this film, so I'm just going to quote one of the Vimeo commentators:

Tavet Gillson 4 days ago This is a courageous and penetrating exploration of onanistic solipsism and male creativity vis-a-vis the archetypes of the headless poly-racial auteur and the hyper-sexualized castrated male body. The physical rape of "MC Stevie's" head by his violent, inchoate, decapitated self symbolizes the artist's struggle to transcend the mind-body dialectic by means of a return to sexual primitivism. The parade of deformed goblins within the anal, pre-verbal world of the "drain" suggests a form of wished-for pregnancy — a yearning to be "filled up with beautiful, strange, babies" — but ultimately we return to a binary universe in which the "bone" becomes the brain and the face/head is reduced to a mere tool for masturbation.

Pretty much sums it up.
