^Everything about this lol
The show, in my opinion, is a show that kind of has everything a Broadway show should offer. It has spectacle (which the Land of Oz should have), it has characters the audience fall in love with, songs that advance the story along and has people buying the cast recording in droves, and has a story that people from the ages of 8 to 80 can enjoy and find something to ponder about.
I've seen WICKED a lot. And every time, I see a wide array of reactions. After the show, I typically see little kids singing/humming the songs and talking about the "scary monkeys" and the "big dragon", I see the teenage kids (both boys and girls) talking about the friendship and how they want to sing "For Good" for their Graduation, and then I see the parents talking about how the political atmosphere in Oz is similar to our own and how the power we give to officials can give them enough influence to sway public opinion for good or bad.
The show reaches out beyond "fluff" I think. I don't think fluff shows can really garner such a wide reaction from the audiences, and keep them coming back for more.
