J.K. Simmons plays a nice, wonky engineer who expels his hippie son in the late ’60s for loving rebel rock. Years later, the grown kid (Lou Taylor Pucci) returns with a benign brain tumor, soon removed. But he’s mute, and only those groovy old tunes can open him up for new grooving. A factual essay by Oliver Sacks has become Jim Kohlberg’s puerile uplifter, perhaps the squarest film ever made about a guy who craved hipness. With Julia Ormond, Cara Seymour. (2011) — David Elliott
