I just watched Blade the other night. I had seen it before but this time I noticed something wrong with it. So, human blood contains mitochondria and vampire blood doesn't. Vampires drink human blood because the mitochondria in it is what sustains them. Deacon Frost wants to summon a demon that will turn the entire world into vampires, but if he does that then whose blood will they drink?

Do you guys have any other ones?
