they read nothing but comics

I think one of our problems now is that we have guys who love comics. But they read nothing but comics. They’re people with limited education and limited views, so they keep feeding back into comics what they’re reading in comics. What comics need is an educated mind, a cultivated mind — it needs somebody with other ideas to come in, and it needs to step away a little, I think, from the trite, the cliche material that we’ve been dealing with all these years.
