Don't go in with any expectations. KA is unlike any Cirque show and I'm glad I read the yelp reviews first. You won't see alot of acrobatics being done, but the storyline and stage effects more than compensates.
The artistic direction was just breathtaking. The stage has been designed to move in so many directions that you just cant wait to see what's going to happen next. There are some confusing parts, so you may want to read up on the story before you watch the show. I wish I did.
Save money and request a spot in section 202. We sat up close and it was a strain on your neck. If you're willing to spend just a little more cash, get the dinner and show combo. We did the Craftsteak + show and it was well worth it.
