I was really impressed with this movie with the way that it navigates a bunch of different kinds of genres in a tricky way, 'cause it is a low-key comedy for a while, but then it becomes a sci-fi film and a legit horror film.

Although it may evoke such films as "Gremlins" and "The Lobster," as well as David Cronenberg's earlier work, writer-director Bobby Miller's oozy, eerie, yet weirdly soulful yarn feels like an original.

Master Cleanse isn't the easiest film to open up to. But Miller knows exactly how the third act should play, and he manages (thanks in part to the increasingly intriguing creature work) to reach an emotionally satisfying conclusion.
