There are some movies that gently welcome you in with a warm guiding hand, and there are movies that thrust you into the deep end of their drama with a sharp shove to your spine. Medusa Deluxe is the latter, chucking audiences into the panic, gossip, and paranoia that infests the backstage of a regional hairdressing competition in England after one of the contending stylists is found scalped. If this description of the basic premise made you do a double take, I think you'll love every unapologetically sordid moment of A24's latest gem.
