This is a very classy horror movie. Essentially it's a one-man show, and it's been directed and acted with a lot of style.
The structure is so tight and the dialogue so convincing that it would almost work just as well as a play. It consists of a series of rhetorical questions. These questions - about love, life and more sinister things - are directed at a comatose woman on a couch. She looks like Allison Janney in American Beauty, staring off into space. The questioner is clearly a deranged man, but in a debonair sort of way. Think Christian Bale in American Psycho, not Christian Bale in that crazy viral video captured on the set of Termination: Salvation.
Things get very creepy very quick, as the man all but molests this helpless woman. The movie has been made in such away as to keep us guessing about what's really going on, and I'm happy to report that the denouement does not disappoint. Conceptually, the movie is quite clever, along the lines of Brent Hanley's brilliant script for the Masters of Horror episode "Family." I was worried it would wind up being an M. Night Shyamalan-style cheat, but thankfully my fears were unfounded.
The centerpiece is the absolute tour-de-force performance by Eric Riedmann. He gets us inside this guy's head, which turns out to be a very scary place indeed.
