In Thoroughbreds, writer-director Cory Finley delivers an astonishing debut. The film features two astounding lead performances from Olivia Cooke and Anya Taylor-Joy as a pair of grim highschoolers. The plot of the film unwinds in four chapters (plus an epilogue), in which information is revealed piecewise and the tension and mystery of this thriller matures into a chilling climax. All the while, the spectator is treated to some stunning cinematography that perfectly captures the pristine affluence of the setting while simultaneously hinting at some dark kernel. This grim tone permeates the film, lending Thoroughbreds an additional layer of significance and meaning.
