I have heard that Footloose the musical did have a fan base of people in their teens, the fans who did the rush line over and over again. (I myself don't remember the advertising, except that the poster was not attractive!) But it didn't find a wide enough audience to keep it running.
As someone who grew up listening to the soundtrack of Footloose, and having seen the movie multiple times on cable (which you consider to be free when your parents are paying for it!), I didn't feel the need to pay the price of a theater ticket to hear those songs and see that particular story played out again. Same with Saturday Night Fever, though I didn't own that soundtrack until much later when I was feeling nostalgic. (And I do mean soundtracks, I don't own the cast recordings to either show.)
Nowadays I tend to see more shows - knowing about lotteries and play by play helps! - and the reason Good Vibrations didn't succeed was because it was just plain bad, and not, in my opinion, a good way to introduce anyone to either Broadway or the Beach Boys. And while I actually enjoyed All Shook Up, I don't think it was aimed at teens...all I could think of was how I wanted to bring my parents to see it. (Sadly it closed before that could happen.)
I do wonder why musicals based on somewhat cheesy, if enjoyable, American movies do so well in the UK...I hear it is very hard to get a ticket to Dirty Dancing, the Musical!
