I am reviewing all the Cirque Vegas shows, so I will add this paragraph comparing each one. I have seen each one twice, so I feel confident in my ranking. My ranking would be 1) Ka 2) Love 3) O 4) Mystere 5) Zumanity 6) Viva Elvis. Ka is the most technically complete, with a storyline, amazing stunts, creative images, stages rotating on axes, etc. LOVE is the most fun and a very close second place. O is the most beautiful. Zumanity is the sexiest, but stunts are just okay. And Viva Elvis could be sooo much better. You can read my other reviews for more info...
Onto Ka... my absolute fave. I didn't expect it to be, as it looked too warrior-like and manly for me from the previews. But wow... this show has it all. The storyline is good vs evil, and you don't really need to know or understand more than that. The swordfights on the vertical wall are incredible. So interesting to watch. And the stages rotate around on axes, so it is so visually magnificent! Theater is amazing, and I've sat in the back and in the middle, and both seats were great. Great soundtrack too. Probably one of my favorite shows I've ever seen in my life. Trust me!
