Las Vegas cirque questions!

Folks who've seen "Ka": how is it? I have heard differing reviews from folks, but I no longer remember how much my tastes meshed or failed to mesh with the people offering reviews.

clauclauclaudia and I have seen Mystere, Le Reve, O, and Zumanity. We usually do at least one show when we're in Las Vegas, and "Love" is dark for the duration of our trip, so "Ka" seems a possible choice.
