Less manipulative than The Blair Witch and a whole lot funnier then Paranormal Activity. Like The Puffy Chair before it, nothing that will really rock your world here, but it's a fine enough way to spend 85 minutes. Chalk up another minor victory for The Brothers Duplass.
Side Note: Greta Gerwig is slowly growing on me. She's either this generation's Meryl Streep or its Karen Black. Not sure yet which.
