I saw Frank Wildhorn's "Dracula" musical during it's preview run in San Diego. It was AWESOME... the story was mostly the Coppola film, but the effects were outstanding and the music was great.
Later it opened on Broadway and became part of the three biggest flops of the decade... all about Vampires. "Dracula" "The Vampire Lestat" and "Dance of the Vampires" all royally bombed.
