I don't mind ghosts. Either they can kill you, or they can't. If they can't there's no problem. And if they can? Well, now you're a ghost, too, so it's on.
Now I'm just picturing BeetleJuice trying to teach the two dead people how to be scary as ghosts and he's like:
"Sever their heads"
While they're:
"Let's hide their phones!"
Are appearing, the likes of which I'd never heard
Now an angry spirit comes back from beyond the grave
"Sever their heads"
While they're:
"Let's hide their phones!"
