I'm a Buffy freak - but i see where you come from, Avatar - the vampires do seem to always be the lamest of the mosters she fights.
They don't fly, or turn into bats, or really have any kind of special power besides super strength. Their faces bump up when they transform from human to Vampire - something I had never seen or heard of before...I've never seen a movie where a vamp's face will morph just to get the teeth out.
