Saw this show this past Monday. Seems to draw big crowds so would recommend showing up before 815pm for a 900pm show. Had a deep discounted GA ticket so just to put in perspective. Reg price is $64. GA seats are in the back on regular chairs so do not expect comfy seating. In fact try not to sit behind anyone because the seating is not theater seating so heads will be in your way. I suggest sitting closer to rail with no one in front of you even if it is to the side is better than seating toward the center and back.
There were plenty of MJ songs, Billie Jean, Bad, I'll Be There, etc so if you like MJs music there is some fair amount of entertainment. However I was not wow'd. Could be in part due to the venue and bad seating. His singing is ok, not great. It is fast moving so that keeps the pace fast and less boring. It is an average show at best so just dont have too high expectations.
