The Twilight Zone is one of those shows that seems to be timeless. It doesn't matter that it originally aired in 1959, people still love it. The show usually would have a surprise ending and the disturbing and unusual characters and events were enough to draw in people's attention.
The show continues to be one of the most popular shows and is often listed as one of the greatest shows of all time. The show ran for five seasons and 159 episodes, all narrated by Rob Serling.
The episodes would start with an introduction by Serling, for example, "You unlock this door with the key of imagination. Beyond it is another dimension: a dimension of sound, a dimension of sight, a dimension of mind. You're moving into a land of both shadow and substance, of things and ideas; you've just crossed over into the Twilight Zone."
