Best: The original Twilight Zone
Too many good and creepy episodes

Freddy' Nightmares (not listed): I think this was the goriest of horror anthology shows, at least on regular television.

The new Outer Limits is pretty good. I've only caught one episode from the OG series so I can't compare.

The 2nd Twilight Zone series was good too. The episode were the kid was hella smart and was preparing for a test and the parents were worried...Good stuff

The Hitchhiker was just weird. One episode where the brick of cocaine keeps getting passed to different people and they die over it and at the end the brick spews out all the coke and kills everyone in the room. Strange.
