There were a lot of things wrong with DotV, it got NO promotion until after the critical drubbing, the direction was lackluster (due, I'm certain to a degree to the director having to deal with personal tragedy, I'm sympathetic, but the direction was still lackluster) No show should ever OPEN on Broadway without a full tryout out of town, the critics had it in for Michael from the get-go due to his Vegas stint AND quite frankly, it doesn't seem like vampire musicals are all the rage in New York (I don't think "Dracula-The Musical" lasted as long as DotV did! I'm wondering what's going to happen with "Lestat.") Finally, yes, Michael's decision to play the Count as a comedic character was in error, but the producer's knew what they were getting when they brought him in. He'd done "Phantom," he made it clear he didn't want to redo Erik and that was the end of it. If they were bothered by that they should have cut him loose from the beginning.
