Sometimes we need others to refresh our memories. I agree with the assertion re THOU SHALT NOT was a potential ultimate stinker, because the creators were such talents -- Stroman, Connick, and that company of performers, all wasted, with the exception of Butz, who managed to score. You expect more from such components. But Crawford's return aside, didn't we all have zero expectations of VAMPIRES? So in a way, it was ... predictably bad. Then you have shows like CARRIE, which had some of the most embarrassing material ever presented (the pig blood hunt) ... and also Betty Buckley breaking your heart singing "When There's No One.." on an empty stage. To me, a real train wreck can't have such moments. CARRIE is easily picked apart in hindsight ... but you know what? It had riveting components. It had real ambitions, some high style in places, and some exquisite stuff (the mom/daughter duets) in the score. Anyone who owns a bootleg copy -- many are in circulation -- can play you stuff that is unforgetable.
