Film is a truly magical medium. You can create illusions of reality, make people think they've seen things that they really haven't - like blowing a guy's head off with a shotgun.

When a guy gets the top of his head lopped off, are they applauding that some horrible thing happened to a person, or are they applauding how it was technically pulled off in a realistic way?
