Saw this tonight and gotta say, I really enjoyed this show. It's really smart of them to use the Dangerous tour as a framing device and it really made the transitions between book scenes work smoothly. And even more, it added stakes to the show. Most bio-musicals don't really seem to have any forward momentum outside of the progression of time, but with this, the rehearsal process added a sense of urgency to the main story and the documentary filming allowed us to really see the creative process that MJ goes through, with the help of the flashbacks. The ending felt a little abrupt to me, but watching videos of the Dangerous World Tour, I can understand why they ended it as they did (though I still felt Thriller and Man in the Mirror seemed to slot in weirdly).
Myles Frost is of course incredible (anyone playing Micheal Jackson has to have moves, but boy can he dance!), but the ensemble is really working out there as well. Not to mention the sound and lighting design, it really gives you that full production feel you'd want from a Michael Jackson musical.
As someone who knows a lot of Michael Jackson songs but not much about this tour, I still felt this was really engaging, and dare I say thrilling. It really is the best bio-musical I've seen in a while, and I'd slot it just under Jersey Boys which still remains my gold standard.
