I'm am not sure how some people said they got "bored" with O. I've seen several Cirque Du Soleil shows and this one was one of my favorites, hands down. Although - I must say - some acts (like the high swinging boat) you may have seen at other shows, but they put a different twist on it which makes it ok.
To me, the most fascinating thing about O is how quick the water moves. You see people walking over it and in the next minute, acrobats diving into the same spot from 40feet high. The production is mind blowing.
And yes, there's really not a plot. Like most of their shows. It's a fancy circus anyways. There are clowns, acrobats, music and lights. It's suppose to be amusing and not necessarily tell a story, like the Michael Jackson one, for instance. It is suppose to be entertaining and it surely is. You look around and see grey-haired people with their jaws dropped in amusement. It's a beautiful thing.
I was lucky enough to get amazing seats and I was so close to the stage I could actually get some mist of water on me. Fascinating. It was expensive $180 per ticket, but totally worth it.
