Finally got to see O after so many times visiting Vegas. Overall, the show's spectacular just like most Cirque du Soleil shows usually are. O is a water show, and the way they utilized that stage was amazing. My favorite part has to be the performers swinging/flying in and out of the water stage. So much skills within the show... worth every penny.
My only complaint is that there's so much going all the time on stage to the point where I don't even know what to keep my eyes on.
