I've never understood why it isn't standard practice to decapitate any and all 'killed' enemies - especially vampires, werewolves and zombies. Only that liquid-metal terminator comes back from losing their heads.
Or at least a bullet through the brain for humans. That would stop those tedious last-minute-baddie-staggers-out-from-the-mist-forcing-our-hero-to-one-final-stand. Yawn.
..and must there always be a lame speech before the baddie shoots the goodie giving the goodie ample time to escape/be saved!!
My favourite line from a movie:
"When you have to shoot, shoot, don't talk" -Tuco, The Good, The Bad, and The Ugly
