The sense of cinematic focus is evident throughout the film’s soundtrack, whether recasting “Seasons of Love” as a muscular new crowd-pleasing opener or torching up “Light My Candle” and “Take Me or Leave Me” several degrees via duets that now feature Rosario Dawson/Adam Pascal and Idina Menzel/Tracie Thoms, respectively. “Love Heals,” a previously unfinished Larson overture, now serves as the saga’s warm coda.
