I think is stupid this sort of snob, for popular and hit show as WICKED...
Piazza and Wicked are totally different kind of musical, and the wonderful of musical theater is that we could see intellectual shows as Piazza and funny and extravaganza shows as Wicked...
I love both, but I think that is thanks to hit shows like WICKED that musical theater will survive...if all shows are like Piazza unfurtunatelly musical don't conquer large young audience and young audince is the only future of musical theater don't forget!
Both musical in their different styles are masterprice for my opinion.
Sondheim and Guettel are genius for intellectual musicals, Schwartz, Menken and Lloyd Webber are genius for the popular musicals...
After some people hate pop and love more jazz or rock, but It's a question of personal opinion....not?
If you don't like the messages from the crazy fans of WICKED don't read them!...It's so simple!

If you continue to protest about it, is because you're only gelous or envious for the mega-success of WICKED or you're masochist to read a thing that annoyed you...
This board offer different and interesting subjects, like musical theater offer different and interesting styles...
After that I think Wicked is an amazing modern musical, who offer serius subjects in a movin, funny show and story with a tuneful and beautiful score, right for young and old people...
