I have always enjoyed Cirque du Soleil shows, and this time is no exception.
This show is mainly acrobats and clown interchangeably performing, giving you moments of tense and excitement, and then sometimes funny. I would say that personally I do not care that much for the clowns, but of course I also understand that you can only have so many acrobats performing, so clowns do occupy some of the time to give you enough "space" in your mind to digest all the amazing acrobats' performances.
As a conclusion, I really like this show, and I think anyone should go see it when they are in Vegas!
