I went with my mama to see this show recently. While I would easily categorize this as the worst Cirque show I've seen (I've seen all of them in Vegas except Mystere), my mom did like it. It's a shame I didn't like it; our seats were great (6 rows from the front, dead center).
I felt that as a whole, quite a bit was unsynchronized, and the show made stretches to incorporate acts with the music. I mean, most acts were fitting to the music, but some definitely wasn't.
In terms of the stage, I also felt that this show had a lower budget than most of the other shows. It sometimes just felt cheap and cardboard-esque.
We caught the early Friday show. I was surprised to see probably 2/5 of the seats empty as well.
