This makes me feel rather relieved that the suggestion of a DS musical, bandied about several years ago, apparently came to naught. On the outer stretches of MAYBE, it might have worked out, but the track record for this genre of entertainment, vis-a-vis vampires, has not been promising. Some things are best left in non-musical form, though either drama or black comedy would work for me.
I once saw Frank Langella on Broadway in "Dracula", egads, it's almost 30 years ago, and THAT was a grand experience. (However, I didn't much like the film.)
