See it if you are looking for a fun thing to do with a group that takes you around town a bit.
Don't see it if you are interested in sight seeing. This is more of a interactive experience and not so much about learning culture.
See it if you want funny, entertaining, sexy and ever changing (they keep changing the leads with current actors/actresses)
Don't see it if you want a serious, relevant, thought-provoking. This is more sit back and have a great time and not have to use your brain.
See it if you love South Park, you enjoy playing cards against humanity, are not offended easily and love to laugh your head off.
Don't see it if you are offended easily or take things too seriously.
See it if even if you've never read the book or seen the movie. It's an epic in the making, skillfully acted, cleverly staged and brilliantly sung!
Don't see it if if you want glamour, glitz or fluff. This is raw and important.
