The good: The skill of the performers was great. They did some really great feats of strength, dance, agility and high wire acts which made me worry for their safety.
The bad: The story was really hard to figure out so it seemed more like a jumbled mess of stunts with no commentary or other clues as to what it all meant. All 7 of us in our party felt about the same way.
I've seen a couple of Cirque Du Soleil shows and, contrary to what another commenter said, I thought this fell well short of any of those.
