The Twilight Zone (1959 - 1964)
More fantasy than science fiction.
The Outer Limits (1963 - 1965)
More science fiction than fantasy.
I have a first-hand story regarding that great and often-fought battle.
Years ago I was visiting my neighbour. The food and drink came out, but nobody got drunk. The ensuing discussions were of the type expected at a friendly get together.
It happened. Scott, boyfriend of my neighbour, seemed to have a problem with my holding The Outer Limits in the same esteem I did The Twilight Zone. "Oh, come on, man. The Outer Limits was so bad. There was that episode that was so typical. The one with the robot boxer."
A challenge. I was thrown back into the ring: "That episode was called 'Steel'. It starred Lee Marvin. And it was a Twilight Zone episode."
Passion. The fists flew. Well, he pointed. "You're wrong." And continuing variations on that theme.
I went back to my apartment, and from my bookcase I pulled The Twilight Zone Companion (Marc Scott Zicree). Back to the battlefield.
With the book opened at the proper page, the chapter on "Steel", Scott's jaw dropped. In the manner expected of a soul converted by a well-placed "K.O.", he emitted a feeble, but emotive: "This is a conspiracy."
On such matters, don't argue with Uncle Simon.
No. "Uncle Simon" is a Twilight Zone episode.
