I've seen quite a few Cirque du Soleil shows in my lifetime, and this one is very good. It's very different from the "classic" Cirque shows. There's more interaction with the audience, more dialogue, most of the show was in English (two songs were sung in the Cirque language) and it's definitely very risque.
I agree with the other reviewers that this show is more of a burlesque show than a classic Cirque show. There is one contortionist act, which was my favorite - very sexy and clever with a unique backdrop (I won't spoil the surprise). More dancing is done instead of acrobatics. That being said, each dance is still unique and beautiful, with gorgeous dancers doing a fantastic job.
Come with an open mind and a sense of humor. You will have a wonderful time. And yes, you will see boobies.
