The result is a messy yet ambitious movie.Her Smell is exhausting to watch. Partly, that’s due to the structure, which separates the action into a loose five acts, demarcated with home footage of the band in happier days. But the run-time of two hours and fifteen minutes means that things start to lag in moments that should feel exhilarating. The first sequence, in which Becky wanders backstage with her baby as her friends and family follow her apprehensively, each passing second making it increasingly clear that she’s not in any condition to care for her, is insanely stressful. But other scenes would benefit from a trim to sustain the emotions and tension. At some point, you lose focus, wondering when and if, this all will end. And when it does, you’re kind of too far gone to care.
