OK - the show is a FIVE. I don't deny that. The music and performance is the best I've seen in Vegas. This show was just fantastic. The sound quality is amazing and THERE ARE NO BAD SEATS. Buy cheap seats safely, nothing much gained by moving up a level. It's a circular theater so you are in a good spot.
I just had to deduct a star for two reasons:
1) The concessions were atrocious. I can kind of accept that I'm getting ripped for $12 popcorn, but at least pop the kernels. I could pay $15 for a jack and coke, just pour it fair. We paid $60 for two drinks, a pretzel, and a popcorn. The pretzel was awful, the popcorn uncooked, and the drinks weak. You gotta meet me halfway. So maybe just eat/drink first and avoid this.
2) The seats aren't comfortable. They are oddly small. If you're 6'0+ it's going to be tight. If you're bigger (I'm a L/XL, around 6'1) and I had to basically cross my arms to stay off the seats beside me and I didn't even have room to cross my legs.
That's just some feedback FYI - it is a GREAT show. By all means go see it, it's wonderful and you won't regret it, just keep those two things in mind.
