I support this very excellent work . . . By EVERYone. All aspects . . . Stunningly creative, intelligent. I would not even write a review if I wasn't unable to find my two misgivings anywhere here addressed, so I'll add: the musicality.
Difficult for me since I don't, in the main, enjoy musicals. One, maybe two exceptions. This is not one of them. HowEVER. I do see, once the 'mystery' is solved, why. Literally.
Additionally I appreciate that the full spectrum of feeling is explored as an intrinsic aspect of the nature of the entire work and music may be the only way to achieve a certain aspect of joy.
Then there's the pace. This was just too long by one or two episodes. Too slow in some spots especially given the complexities and discomforts. Asking your audience to sit and simmer in the soup is, I think, too much.
But a difficult conclusion at which to arrive given the amazing work overall.
My solution: to click on ALL the tens in the reviews and rate an 8/10.
