Mystere has a few extraordinary acts of strength and balance that will stick with you for years and those two acts alone make this worth seeing, but be prepared for the confusion and yawns that accompany those acts.
Everything else is truly bizarre fluff. I felt like the guy from "Knocked Up" watching this, only I didn't need shrooms to feel tripped out of my mind. The comedy and scenes with dialogue were not for my husband and I, and like some others have already stated, I felt bored multiple times. While most of what the clown prior to the show did was entertaining, I myself wouldn't want popcorn dumped over my head and I felt a little bad for those unlucky few who had this happen.
What bothered me most was that there was literally zero plot or sense to make of Mystere. I guess that's the gimmick, but it made the show feel like it was assembled of all the acts they couldn't squeeze into the other Cirque shows.
My two cents: You cannot go wrong with any Cirque du Soleil show, but this is NOT the one to see unless you have children with you.
