In the Broadway run, that sun shines brighter and clearer- the show-choir costumes are shinier, Danny Mefford's choreography has more room for ice-skating action, and set designer David Zinn has even deployed a revolve, though, delightfully, it's used only to turn a dinner table. You miss the closeness to the actors, since director Jessica Stone has done such lovely work in getting the cast to capture the micro-grimaces of high-school awkwardness, but the essential delicacy of the show is intact.
