Mystere was my first Cirque show. It is a wild, colorful, well performed show. The acts are impressive; they're performed by true athletes and artists. But, I have to say that I preferred O to Mystere. I liked the storyline better. Mystere is very abstract as other posters have stated, so you might want to research it a bit before going in, so you don't feel lost. I'm glad I saw it. I just wish I knew what was going on the whole time. Still, I am in awe of all of the performers.
