Ok, so let me start with... I LOVE Cirque du Soleil. I have seen at least 10 different ones. 'O' is one of my least favorites. I don't think the show is bad, it's just not for me. So, this is why....
I LOVE water. I love to swim, but why is this show so much diving? I feel like I'm at a diving and swimming competition. I got so sick of the same old thing in this show. I think there is just only so much you can do with water. It seemed like the different scenes were very disparate. I wanted this show to be really good, but they rely to heavily on the water gimmick. In most Cirque shows, there is a 'oh my gosh' feeling, and this one just doesn't have it.
The theatre is beautiful and comfortable. The ceiling is amazing. The stage/pool is amazing, I can't believe that they have a pool this size with all the engineering behind it in the Bellagio. It's amazing. The costumes (especially the black and white ones) are great!
We stayed at the Bellagio and planned well in advance. The Bellagio has tickets set aside that you can purchase in a Bellagio guest section. Our seats were great. I'm glad I went but I wouldn't ever go back (like I have with Ka and Mystere) therefore the 3 stars.
I'm glad I saw it, because I love Cirque. I wouldn't go back. If you want to see a Cirque show and can't see them all (and there are so many in Las Vegas now) don't go to 'O'. Go to Mystere or Ka.
