A friend of mine, Ralph Hanson, shared a link on Facebook to an incredibly interesting column over at the Comics Alliance. In the column, Chris Sims answers questions weekly. Last Friday he was asked, "Q: On Scooby-Doo, do you prefer the monsters to be real or people in costumes? -- @heythisisbrian"
Chris' answer is fascinatingly brilliant. In short, he says that the monsters on Scooby-Doo must be people masquerading as monsters because the world is full of bad people who lie to kids using superstition to scare them. Scooby Doo teaches them that the best thing to do in the face of fear from superstition is to think.
