Just got back from seeing this a second time and, if anything, my estimation of it has only gone up (and it was pretty high to begin with).
There is something just so achingly beautiful about this production. It helps that SPRING AWAKENING really lends itself to this signed/spoken/sung approach. Much of the plot revolves around communication (or the lack thereof). So, for example, at the beginning when a signing Wendla asks her speaking mother to tell her the Facts of Life, there is a whole 'nother layer added to the scene. And this dynamic continues throughout the piece, highlighting & illuminating things in interesting and unexpected ways.
And then, of course, there is the esoteric alt-rock/abstract nature of the music & lyrics. When they sign/sing "Oh, I'm gonna bruise you/Oh, you're gonna be my bruise", the expressive ASL gestures adds a choreographic element that you don't get in a traditional production. Again, this happens over & over throughout.
A second viewing exposed so many riches that escaped me the first time. So many details of performance, movement, direction. The cast is superlative -- even more impressive than on first viewing. And despite what singingbackup experienced, there was certainly NO lack of energy. Both "Bitch of Living" and "Totally F****d" darn near stopped the show. (Isn't it great to be in an audience who really appreciates what they're experiencing?)
There was another Q&A after the performance, and despite a leading question or two, there was no mention of any future plans for this production. (I also spoke to someone Very High Up after the performance, but with the same result.) And that would be a crying shame. I think this would be a shoo-in for a "Best Revival" Tony nomination. But, beyond any awards consideration, I honestly think this is a production that deserves to be seen by as many people as possible.
It's just that powerful. It's just that good.
