Black Mirror first season minus the first episode seems to be this generation’s version of the twilight zone.
I stopped watching The New Outer Limits (1990s reboot) after the first season. It seems half the episodes were about some right-wing, often Christian, dystopia. Many episodes had environmental extinction/global warming themes.
I did like the Patterns episode of Night Visions.
And The Conversation episode of The New Outer Limits.
