Zach’s girlfriend Beth miraculously returns from the dead, but she’s a little different now …

This movie works only so far as Aubrey Plaza’s performance gives it some soul. Her mix of quirkiness and rage gives depth to an otherwise slapstick parody of zombie apocalypse movies that feels like a sketch comedy stretched well past its breaking point. It has its enjoyable moments, and is sometimes genuinely funny, but doesn’t quite deliver on its promise.
