Yeah, I don't know about that. Wasn't it Potter Stewart who said "I know it when I see it"?

Yeah, it was. I looked it up, and his quote would seem to apply here, but for the "motion" picture aspect: "I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description [hard-core pornography]; and perhaps I could never succeed in intelligibly doing so. But I know it when I see it, and the motion picture involved in this case is not that."

Bears, beets, Battlestar Galactica.
