This is my favorite Cirque du Soleil show. The theater is wonderful and there is no bad seat. The costumes were out of this world and the use of water was astonishing! I thought KA was elementally intriguing but O just blew my mind. This show is a must see for anyone visiting Las Vegas. You have to see it, at least, once in your life time. Bravo to the cast and everyone who has helped put this extraordinary show together.
