I realize this is a huge challenge ... adapting material into a musical that has previously been adapted as a musical.
There are only a few instances I can think of where this has happened ...
Peter Pan (three times, if you count the Disney animated version).
Cinderella (Disney and Rodgers & Hammerstein)
My Sister Eileen was adapted as a musical film (of the same name, starring Janet Leigh, Betty Garrett, Jack Lemmon, and Bob Fosse), then adapted again as Wonderful Town on Broadway (starring Rosalind Russell and Edie Adams).
Two version of Phantom on stage, etc.
It's a daunting task to try to write a full original musical score for something that already has an established musical score (in the same or different medium).
Especially one with a score that so many people know and love.
With the recent film-musicals-to-stage-musicals, they have kept most of (if not all of) the previous scores and just added songs to it, rather than start over.
Like I said, I would be open to it. But these songs just don't "land." They feel right and sound fine, but the melodies don't linger. None of them. They run all around the scale and then head for the door.
Then you get Pure Imagination and go "aha!" It's not just that the song is familiar. The way it's written allows you time to enjoy the melody. The other Bricusse/Newley songs do, too. It's just a stronger construction.
I think I'm also disappointed here because Hairspray remains one of my favorite Broadway scores in recent years. Solid, simple, but clever, soaring melodies. I don't think there's a bad song in it.
