Neither. And the worst part about Vampires Suck? The wasted potential. I've been watching irreverent parodies for years, Naked Gun and it's sequels, Loaded Weapon, Airplane, etc. Just yesterday, I was watching Hot Shots: Part Deaux.
These movies are the same genre as Vampires Suck, but why are they better? Humor, fun, and they're own identity. They have some semblance of a plot, and the characters, while being a mockery, are actual characters.
So in the hands of someone with talent, this movie could have been gold, and that's why it's so bad. Twilight never had any potential beyond the words Vampires and Werewolves.
