In this gross but smart comedy from Jacob Vaughan, a man's stress grows into a monster that explodes from his rectum.

Review: 'The Human Centipede' Meets 'Gremlins' With Grotesque Horror-Comedy 'Bad Milo'

Review: 'Bad Milo!' Starring Ken Marino & Gillian Jacobs A Ridiculous But Respectful Horror Comedy

Duncan's stomach problems in times of stress turn out to be a monster that emerges and goes on the attack. Screams of laughter ensue.

In the comedy “Bad Milo!” Ken Marino plays a mild-mannered accountant with a vengeful critter living in his colon.

A crass comedy about a stressed-out guy with a monster living in his bowels turns out to have a few good belly laughs.

By straddling a spectrum of bad taste that ranges from "Basket Case" to "Family Guy," "Bad Milo!" is weirdly satisfying.
