To me it felt like the teacher coming in on the class being rowdy or fighting, everyone stops what they are doing and behaves, then the teacher tells them they are getting ice cream or whatever, everybody hugs and cheers. Breaking the 4th wall in the worst way possible.
It's so screwy. The problem is that there's almost no comparison. With a play, they're doing the same thing every night. But it's basically like an episode of Criminal Minds being aired live and having the showrunner walk in during the middle of a court scene to tell everyone they're getting a Christmas Special for the first time and all the actors clapping and hugging each other before going back to portraying a serial killer as if nothing happened.
