Let’s agree on one thing: Deaf West’s excellent Broadway revival of “Spring Awakening” is a fine production currently showing at the Brooks Atkinson theatre in a limited run. The sets and lights are magnificent. The staging is right. The actors are completely superb. The effort is noble, but perhaps, imperfect in the execution of its essence, and it is in that vacuum of those slight flaws in amber that this review reflects — to make you think and wonder in preservation and ponder beyond the simple joy of watching a few Deaf actors on a live Broadway stage.
