Almost unbearably sad not because of the story but because it was Anton Yelchin’s last performance. He had a talent for picking wonderfully horrifying indie projects. “Thoroughbreds” is a worthy companion to “Green Room”; both are dark and highly distinctive. 

Which isn’t to say that it’s Yelchin’s movie. Both leading actresses Olivia Cooke and Anya Taylor-Joy are pitch perfect here, performing at a level of confidence far beyond their years. In Cooke’s case she elevated a part that is a bit too on the nose, but her chemistry with Taylor-Joy is utterly convincing.
