Agreed, but I'm talking about whether they will actually do it. Besides, any version of the JL must necessarily have more than one fanciful element. That will make it considerably harder.
Apropos of not much except the idea of plausibility: I still haven't forgiven Matheson for the idiotic science he used in The Shrinking Man. The psychology, characterization, etc. was spot-on, but the descriptions of what was actually happening to the guy made no sense at all.
I'm not sure anyone ever accused Richard of being a hard-science guy. He's more rooted in the Twilight Zone
school of sf/fantasy/horror . . .
