I've only been to this show and "O" at the Bellagio. I prefer this one because the clowns are not so annoying. The story line is interesting, but the acrobatics and rotating floor make it happen! I can't peg exactly what was so impressive about it, it was just a fun show with something always going on. The characters were really cute and did a great job. We sat in the 2nd row and I really loved our spot. A few rows back might have been better, but we were practically in the show.
One thing I do NOT like about cirque shows is the fake plant they seem to have in every show. I think it's obvious enough that the person they pull from the crowd is part of the act, but maybe it's for the kids? Anyway, the plant in this show was actually a pretty fun one. He happened to be sitting right behind me. Also, I should note that I saw a lot of kids at the show, so I suppose it's kid-friendly.
