Twilight Zone was just a bit before my time but I do DVR a lot of the shows around certain holidays when they do the episodes non-stop over a weekend, like on the Sci-Fi channel.
I really enjoyed Rod Serling when I was older and he did Night Gallery. Then I found out he did Twilight Zone before that and began to watch the reruns.
Serling had a way of presenting things that weren't gory, not bloody, but possibly twisted / distorted / evil in its own way. At the end of the show, you didn't want to turn off a light in your room, hear a car drive by your house or answer a phone call.
