‘Zarkana’ fast, lively but lacks point of distinction

Las Vegas Review-Journal: Of course, Cirque du Soleil wants you to see all of its Las Vegas shows. Knock yourself out, I’m sure they would say.
But if you take them out of the order of arrival and start with “Zarkana,” I don’t think anyone would argue with that either.
Not that you’ll see ads that say, “This one’s better if you haven’t seen our other shows.”
