It's more like a 3.5 star rating. As it is with Cirque shows, there just seems to be a lot of random stuff going on. I didn't notice a storyline (so far only KA has one), which is pretty normal for a Cirque show. I definitely wouldn't put this on the top of my Vegas Cirque shows. I noticed that one act from KA wasn't in this showing (even though I see a picture of it here on yelp) and a co-worker had told me about it. So maybe they're changing it each time or something. *shrugs*
Not too much stood out to me in this show so it's just okay. For now, at least. Who knows what will be changed in the future.
I've seen all the Vegas Cirque shows...
1. KA (MGM)
2. Mystere (TI)
3. "O" (Bellagio)
4. Michael Jackson Immortals
5. LOVE (Mirage)
6. Viva Elvis (Aria) *gone
7. Zumanity (NYNY)
8. Criss Angel Believe (don't bother with this show)
That's pretty much the right order in terms of preference, too.
