What strikes me most is how vividly I recall my family watching this show together each week when I was young; it originally broadcast during the time my father was just two years old. That’s why it has stayed with people so long—similar to the initial run of The Twilight Zone and even the later version from the eighties—because it offers a bit of everything, presenting a fresh narrative in each installment. It's almost as if American Horror Story aspires to achieve what this show does, but struggles to conclude its stories within a single episode, or at least doesn’t manage that conclusion consistently enough to ensure viewers return week after week. The variety it offers means the tone shifts from entertaining to frightening, and that really depends on which particular story you're watching.
