Saw the show in NYC last year and again this month. The show used to feature English "rock-opera" vocals... and now it just features the Cirque gibberish you may be used to. The English lyrics were utter nonsense and I thought the show would have been improved without them. It wasn't. Now the characters just stand on stage and sing to the audience but the audience has no idea what they're saying. (Two of the people I went with thought the words were in French and they just didn't understand because they didn't speak it.) It's like they didn't bother to change the staging when they got rid of the story, and the end result is awful. Plus the female screeching has got to go. Bring earplugs.
The second half of the show features some really good acrobatic acts. The trapeze is one of the best out there, though Mystère's new trapeze act certainly rivals it and makes Zarkana feel redundant. We've also seen the Wheel of Death before in KÀ. But the handbalancing scene is stunningly beautiful, and the final group acrobatic number is excellent.
Apart from that, though, there's not much to write home about. Most of the music is amateur and forgettable. The stage is pretty at times, especially in the first few scenes, but the projections get old after a while. The whole space scene is complete nonsense, out of place and entirely unacceptable. I was pretty bored up until the last couple acts, so I can't recommend this show.
