The Power of the Dog (Netflix, 12.1 -- formerly 11.17) is a chilly and perverse cattle-ranch drama that insists over and over that it’s a very bad thing for toxic males to suppress their homosexuality. (HE agrees.) Campion is a top-tier filmmaker and there's no disputing that this is a quality-level effort, but Dog‘s milieu is grim and stifling and melancholy, like the dark side of the moon.
