I went to a postmodern dance production at a local college a few years ago. I didn't know exactly what I was getting into until I got there. The dancers were all dressed in white, and they did not seem to have any rhythm or rhyme to any of their movements. The whole, two-hour production seemed random and chaotic.
Some people out of the audience got up and joined the production at different times throughout the show. That was really confusing, too. I have to say that I did not enjoy it very much. It was like watching a train wreck or being stuck in traffic. I couldn't go anywhere and I couldn't do anything at all about it.
