I just found it by chance a couple years ago, and its entered regular Halloween rotation. It's also a very silly movie at times, but it has something to say. If it weren't played straight, it would undercut the whole thing.

I can't help but imagine that, if they tried to make it today, it'd just be noted to death by the studio. "Say less, quip more." Then you'd get a ho-hum vampire action-comedy with a whiff that it was something better in a previous draft... like Renfield.
