Well, I actually quite enjoyed this. I really didn't know what to expect.
I'll try not to spoil too much, but you can rest safe knowing that they cover as many michael Jackson favorites as you can fit into a 80min show.
There are lots of things happening all over the place that it's sometimes hard to keep track. People climbing on the walls, people flying from the ceiling, etc.
They also tell kind of an interesting story with 4 kids who get trapped in michael jacksons world, which revolves around famous pieces of his clothing (for example the glove).
The best way I can sum it up is think about all the cool dance acts on America's Got Talent the past few years and imagine if they incorporated a bunch of those top dance and acrobatic acts into a giant cirque de soleil. That's what Michael Jackson One is. The fact that I like America's Got Talent explains why I'm rating this 5 star.
