Despite appealing performers, Hollie Meyers-Shyer’s Home Again (D+) misses the mark in nearly every way. Reese Witherspoon plays an L.A.-based single mom whose brush with three plucky young filmmakers (Pico Alexander, Jon Rudnitsky and Nat Wolf) prompts an unconventional living situation. Candice Bergen and Michael Sheen are among those in the ensemble wasted by a phony series of unbelievably benign events. Nobody behaves convincingly in their designated profession. The biggest first world problem of all is a rom com that’s not funny or charming.
