"Tár," arguably the best film of 2022 no matter which motion picture the Academy decides to honor, is a movie about contemporary culture wars that refuses to participate in them. It portrays the generation gap that yawns between liberal elders and progressive juniors in many cultural institutions, illustrates the potent influence of cancel culture and #MeToo, and uses both forces in a believable (if hallucinatory or supernatural) way to propel the spiraling descent of its title character, Cate Blanchett's fictional conductor, Lydia Tár.
