Link to Film Threat's review - I think they like it.

"Gregory Hatanaka’s “Mad Cowgirl” represents the most visceral and explosive cinematic mind *beep* since Stanley Kubrick tossed Keir Dullea into the psychedelic vortex. Rarely has an experimental film come along like “Mad Cowgirl” that can take reckless and daring risks and earn a payback on its artistic gambling with a tenfold return. Theaters showing “Mad Cowgirl” should install seatbelts, because audiences are in for the ultimate wild ride."
