I just finished the first season of 36 episodes, several of which have become iconic like, "Time Enough At Last" where Burgess Meredith finds himself to be the last man on Earth after a nuclear war and having all the time and all the books to read endlessly to his heart's content only to accidentally break his eyeglasses. "Third From the Sun" were a scientist working in a weapons factory discerns that the world is about to be destroyed in an impending nuclear war so he makes plans to escape it in a spaceship traveling to a another world that may have people that are similar to them called Earth. "The Monsters are Due on Maple Street" another contemporary allegory similar to "Third from the Sun" which posits a story of extraterrestrial invasion which is a thinly veiled critique on the van recent Red Scare. And one of my favorites "A Stop at Willoughby" about a stressed out businessman taking his usual commuter train home after a tiring day at work only to get out at a place called Willoughby seemingly set in an idyllic, simpler time in the past. The twist here though is we find out that he actually killed himself by jumping off the train and the name Willoughby is a reference to the mortuary service ferrying his body to the funeral home.
Things of note about this first season: the famous Twilight Zone Theme music isn't yet a part of this, the music is just some muted strains which I think they still use throughout the whole series to set the the mood as eerie and off-putting. Rod Serling doesn't appear in the beginning as he does most of the other seasons, instead he appears at the end similar to the way Alfred Hitchcock did it on his show setting up the premise of next week's episode. I guess that two thirds or so of the episodes are written by Rod Serling and the majority of those not directly written by him have been adapted for television by him.
The other Seasons seem to be just about as long although I did read on Wikipedia that I think it's the fourth season or so that episodes extend to an hour long each. No matter without commercials these puppies are only about 20 minutes 25 minutes at most so it's easy to tick them off many at a time each setting. Unlike The Amazing Race where those episodes got so long and drawn out especially as it seemed like episode after episode contestants were doing the same thing over and over again. I didn't make it past five seasons. With this show it's only five seasons in total I believe and even though there are quite a few episodes each season it should be much easier to get through. Plus, even though these are all science fiction slash fantasy/a little bit of Horror, they're all very unique. The only ones I intend to skip are the ones that I've seen several times because they are so famous like for instance to serve man where the big twist is people are being served on a dinner platter for the aliens, and the episode where William Shatner freaks out on a plane because he sees Gremlins on the wing.
