Owen Gleiberman Chief Film Critic If Lars von Trier hadn’t grown top-heavy with the mythology of his self-importance (I’d say that happened around the time of “Antichrist,” in 2009), he might have tossed off a movie like “Sick of Myself” — a social satire in the form of a queasy drama of body horror, and a movie whose disturbing bad-boy tastelessness recalls Von Trier’s “The Idiots,” with a touch of David Cronenberg. This is the second feature by Kristoffer Borgli, the Norwegian writer-director whose first film, “Drib” (2017), was a send-up of the marketing industry, and in a way the new movie is about marketing too. This one, though, takes a viscerally upsetting look at just how far an individual will go to gain attention in the new era of social-media addiction.
