Littered with clever dialogue, a beautifully constructed narrative, as well as moments that shift between the energizing and sheer terror, there are a slew of endearing qualities worth sifting through.

Just on a technical level, the film represents such a big jump forward for Saulnier that you should expect the studios to immediately start arguing over which giant soulless franchise should occupy his time in the near-future.

An exciting, splattery, funny genre movie that somehow never once feels disposable.

Scary and funny by turns, Green Room has the potential to become a cult hit, with a genuine midnight movie appeal, and furthers the growing reputation of this young director.

Saulnier’s ability to take a well-trodden road and fill it with grisly surprises is quite something.
