The Twilight Zone was Rod Serling's vision to transform small screen by telling some peculiar tales. His stories are all pregnant with immense existential value. I have watched first few episodes and each one of them contains a self-sufficient story, independent of other episodes. The episodes I have watched, deal very vividly with the matters like loneliness, old age, death and nostalgia.
The opening dialogue(monologue?) in the beginning of every episode, in the voice of narrator Rod Serling is just mesmerizing:
There is a fifth dimension beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition, and it lies between the pit of man's fears and the summit of his knowledge. This is the dimension of imagination. It is an area which we call The Twilight Zone.
Rod Serling was writer and producer of this series and he had taken a great deal of risk when he decided to make something like this for TV. To narrate such ideas, on TV, in sixties, was very audacious and novel. I think he pretty much succeeded in what he was trying to accomplish: Entertaining me and you and all of us. Enjoy the series, with Black & White prints and consummate performers.
