See it if You like to go to the theatre for a fun entertaining show that's fluffy and nostalgic. Also if you are a fan of The Four Seasons.
Don't see it if You are not a fan of jukebox musicals. The audience loves to sing and dance along, so if that bothers you I would stay away.
See it if You love classic shows from the golden age of musicals and you love great choreography. It's nostalgic.
Don't see it if You like something more modern and fresh or something with big names.
See it if You enjoy The Wizard of Oz, it's not as dark as the novel it's based upon. If you like great costumes and dazzling sets.
Don't see it if You like something a bit more edgy or non traditional. It's a very popular show and can be somewhat quirky and cliche.
