"I think you can say more obviously in the framework of an honest-to-Christ contemporary piece so that you don't have to talk in parables, in symbolisms and the rest of it, but this is not to say that you can't make a point of social criticism using science fiction or fantasy as your backdrop. We did that on Twilight Zone a lot, but there's no room for that kind of subtlety anymore. The problems are so much with us that they have to be attacked directly."
