And no, I don’t care if these piles of crap were intended to be cheesy and annoying. That really just makes it worse.
That's overstating the case. It's more like they're aware of the cheese aspect and (at times) embrace it. I mean, these is a show about vampires, after all. Can't take itself too seriously *all* the time.
An example is the Mayor, the big bad from season 3. He's this smiling, likable, mini-golf playing family man. Who just happens to be bent on becoming a giant snake and eating the town. I mean, you've got to have career goals, right?
