Let these lyrics wash over you as the latest examination of office toxicity plays out in a modern milieu: “They just use your mind and they never give you credit / It’s enough to drive you crazy if you let it.” Sam Raimi’s buoyant horror/comedy Send Help (A-) functions as both a delirious deserted island escapade and also a twisted battle of the sexes, with pulp friction aplenty to scratch the itch, feed the beast and satisfy the gods of carnage attuned to his particular directorial sensibilities. Rachel McAdams brilliantly creates a singular character: an undervalued cubicle denizen with mad coping skills who finds herself on shipwrecked shores with a boss most boorish, played with a dashing grimace by the ever-more-fascinating Dylan O’Brien. This deeply entertaining two-hander traces the peculiar power dynamics of two incredibly committed actors, all the while steeped in the tropes of a survival story. This adventurous allegory offers continuous fresh takes and mixed genres, with plentiful splashes of giddiness and gore. Bill Pope’s crystalline cinematography and Danny Elfman’s understated score add zest to the demented dynamics. It’s watercolor meets watercooler as corporate culture get an epic seaside skewering.
