In one scene in the movie, vampire lady is looking for a tasty place to bite Dennis Miller's neck. She sees the chain around his neck and starts to back off in anticipation of a crucifix. But then breathes a sigh of relief when she sees it's a Star of David. Apparently, in this movie, they don't have any power over vampires. That's fine. Then later when all the vamps are dead and the movie is finishing up, they've gotten a Rabbi to consecrate the ground to stop the vampires from waking up. Why, if the Star of David has no power over vampires, do they think that a Jewish consecration ritual would work? [Miller is Jewish, considering the fact that he was wearing a skull cap at the time the Rabbi was performing the consecration. That's why he felt safer using a Rabbi instead of a Christian priest. This is a character decision.]
