Just saw it last week.
It's simply a series of old rehashed "up goes the curtain, there Criss disappears and there Criss reappears" show. They try to mix it up with some Cirque du Soleil dancing and comedy but only about 10% of that was marginally interesting or humorous in the least.
It doesn't completely suck but is not entertaining at all.
Don't recommend it and most other shows would probably be better. I hear the Cirque parts were not indicative of real Cirque shows which are mostly good apparently.
