You may have touched the third rail here, asking what's so special about The Jersey Boys. There seems to be a small group of ultra-loyalists on this site, similar to the "I LLLLLOOOOOOVVVVEEE WICKED, IDINA IS A GOD" crowd. You might see a few flames over this.
Personally, I think it's strange to have an awards show that has as its main recognition a prize for best musical that can be won by a show that contains not a single note of music originally written for a musical. As a member of the Writer's Guild of America, I like our method of giving out awards. We have "best original" screenplay and "best adapted" screenplay.
Maybe, if there is going to continue to be a large number of "jukebox shows" (and producers love shows where they can just license the music and not have to deal with composers and lryicists) there should be a "Best Original" and "Best Adapted" musical. People say that then there would only be two or three shows in the running in each category but I believe the lure of another Tony would tempt more producers to fill the void..
