Writer-and-director Coralie Fargeat’s viscera-splattered follow-up to 2017’s Revenge is about as subtle as a bludgeon to the head, or, indeed, a needle to the thigh. Thankfully, it’s also much more perversely enjoyable than either of those experiences. Just as long as you’re not squeamish at the sight of blood, cascades of organs and the most grotesque prosthetic creations since 1989’s Society.
