Could be one of the most enjoyable Cirque's for me yet.  I am a big fan of Mystere, so if lots of energy and elaborate acrobats are your thing, don't miss it.  Zarkana would be grouped with Mystere and Ka. The remainder of the strip Cirques are very unique and amazing.  I have not seen Chris Angel's Cirque show, and may not as it does not rate well.  I doubt anyone left this show unfulfilled.  Will see again next time in Vegas.
