The show is about 90 minutes long, and some of it is very bizarre. And the acrobatics! They are, literally, incredible. My wife spent most of the show with her hands over eyes. But, having said that, it is a stunner, too, and beautiful to behold.
I don't have kids, so I'm not the best judge of these things but, on a hunch, I'd say you might want to wait a couple years before introducing your kids to this particular circus.

We went to this show in November 2003. At the time my daughter was 6 years old. She absolutely loved the show. She sat there the entire show. That is all she talked about for quite a while afterwards. She was so amazed by all the wonderful acrobatics and the costumes. I would definately love to take her again. HTH
