I'm another one in the minority - we saw this in Boston a couple years ago and thought it was ok. I really didn't see what all the hype was about. My kids (11 and 9 now), enjoyed it, but I certainly wouldn't see a repeat performance.
We also saw Cirque de Soleil and thought is was ok. The acrobatics were really cool, but I'm not into the whole vibe of those shows. And I do love the theater, adore the ballet, and I am a museum freak.
Again, I know I'm in the minority, but just wanted to give my opinion.
