[Dr. Sivana]

They slipped liberal messages into Bonanza and other shows from the 1960s. The Twilight Zone

The one that shocked me on Bonanza was one episode where Widower Ben fell for a beautiful woman (the only women that come into Virginia City are nieces and heiresses) and it pretty clearly implied that they went off on their own for carnal activity. It was confirmed later when he was seeking approval for his dalliance from one of his sons (Adam?), who of course gave it. My response would have been, "Gee, Pa, why don't you marry her and have her die shortly after bearing you a son like you normally do?"

I tolerate the "liberal" episodes of the Twilight Zone because some of them were very pro freedom, and warned of "perfect society" dystopias. Some of the episodes that were viewed as liberal in the day now seem downright reactionary in the modern context. President Trump's favorite episode was when a two-bit hood dies and is given every material he could want, and some beautiful agreeable women to boot, and assumes he is in Heaven, but when he is bored out of his mind after a while is informed that he was actually in the other place.

The worst thing about the "message" Twilight Zone episodes was that they were often so heavy-handed.

Like the town where the sun didn't come up, because everyone was so full of "hate" that they vomited it up. (As explained by the usual kindly and wise black preacher.)

Or "The Monster Are Due on Maple Street and The Obsolete Man.

Or the evil rich man who built a fake bomb shelter to trick people who'd hurt him into begging to be let in.
