The show itself was problematic. The staging, lighting, and music were all excellent. The script and the tunes were not quite there. This was a concept musical without a concept. It could easily have reached out into any direction to be something, but instead came across as tortured art-wank. It embraced every tortured artist motif having trouble with the world and being misunderstood. That is to say, it came across like a goth teenager.
Tangentially, I finally figured out what the Left Behind series is. It's Fundie Fan-Fac. Or maybe it's Bible Fan-Fic. Any way you look at it, it's Fundie's wanking.
