I saw the show in March and am still singing the songs now! The whole thing is hilarious from start to finish and while it's gross and outrageous at times, it actually has a very positive message. I think people who get offended by this show don't see past the swearing so miss the message of the show. The show takes some great swipes at Broadway and musicals and really plays with tropes which is great fun.
I think most people would enjoy this show. Just sit back, relax and prepare to laugh until you're in pain.
