See it if you love classic BIG shows with BIG celebrities and BIG numbers.
Don't see it if you hate Broadway. Otherwise I can't think of any reason not to see it.
See it if you want to see everything a modern musical can-- and should, be. The staging is superb and the cast is delightful.
Don't see it if you're looking for classic "big broadway."
See it if you love drag, big numbers, and sappy Broadway stories.
Don't see it if you're looking for profound meaning. There's nothing unique about the story structure.
See it if you want to see a light and cute show. The numbers are downright catchy and the costuming is clever.
Don't see it if you loathe kitsch incarnate. There is no common thematic thread in the score, as evident by the 16 artists (or duos) billed.
