About five minutes in I decided this was a horrible movie with no redeeming qualities. But when the main cast appeared and the acting went up a notch it was clear that it was trying to be bad. That's where the comedy was coming from. For instance, the main vampire tries to turn into a bat and fails, and this becomes a running bit, with one pretty effective and stealthy pun and several predictable other outcomes. The actresses ham it up, and I thought several were very effective... or at least did pretty well with what they were given. Even for not taking the plot seriously there were a few parts that just didn't work at all. There were more than a few bits that were kind of funny in a surprise left turn kind of way. I wouldn't say that the quality is at Monty Python's Flying Circus level of comedy, but the same kind of absurdity is clearly what they were going for. It's also not your typical time travel movie, despite the title. The parts where that plot gets worked in are pretty random and contribute to the weirdness. I can appreciate what it was trying to do, but in the end I have to rate it compared to other movies. While this is a step above other no-budget productions, it's not that much of a step, and it's only for people who like intentionally stupid things.
