During our last stay in Vegas, we came to see ONE. I loved Michael Jackson (the performer) and always loved his music. Since I had purchased our tickets before the show opened (advance purchase via M Life) we had great seats.
The theater is well designed for a good visual from all angles. All the seats have speakers directly in the headrest.
All of the music was fantastic. Of course, it's MJ after all! Some of the cirque acts were excellent (especially the poll dancer with zero body fat of solid woman)! The only reason I give it 4 stars rather than 5 is for the dance choreography. As with most kids who danced and imitated MJ videos for fun or school shows, I know some of the choreography by hart. I wish they had done it well enough for me not to feel that I could do it better, all these years later. The dancers were good but if they don't know the moves, it's not their fault.
From my understanding, the show is still being tweaked. Although one thing bothered me about the show, it was still entertaining. For most of us that loved MJ, it was a bit emotional at some points of the show and everyone stood up to dance at the end of the show.
If you like MJ's music, you will enjoy the show.
