Minimum

I used to think that television could be potentially the most powerful medium for the dissemination of knowledge that the world has ever known, it could be a very rich and rewarding thing if handled properly and that the problem was in the execution. I've now come, after ten years in the business, five years of which was as a television critic, to taking the very extreme view point. I think television itself is bad.

The idea of television, the act of watching television kills the imagination. It's not like radio, with radio you had to listen, had to make things, you had to build things in your mind. Movies do that. Television is something else again. Television lays it all out there in a very prescribed way and the bare minimum of imagination on the part of the viewer is needed and I really fear for all of us.
