Live, Die, Reprise

When the musical version of “The Lost Boys,” written by David Hornsby and Chris Hoch, with score and lyrics by the Rescues, nails its combination of goofiness and grandeur… Still, the relationship with the film proves tricky. The anticipatory part of horror, it turns out, transfers nicely to the stage — Arden and his frequent collaborator, the set designer Dane Laffrey, are masters of atmosphere. But translating the thriller aspect is harder, and “The Lost Boys” loses its way as it tries, unwisely, to map itself onto the film’s action-packed second half.
