Steve Carell and Timothee Chalamet share several emotional moments as father and son in this real-life addiction drama. But “Beautiful Boy” might be too beautiful itself, depicting its horrors in a gauzy way with a distracting, time-hopping narrative. And the soundtrack of on-the-nose tunes is often cringe-inducing as it comments on the action. Chalamet is James Dean-ing the hell out of the role, though. My mixed review, at RogerEbert.com.
