TLDR: Critics consistently name “To Serve Man,” “Time Enough at Last,” “The Monsters Are Due on Maple Street,” and “Nightmare at 20,000 Feet” among the best Twilight Zone episodes ever made.
On the other end, “The Bard” is one of the most frequently cited worst episodes, though IMDb’s actual lowest-rated entry shifts between a handful of weak season four and five outings depending on when you check.
Across 156 episodes and five seasons, The Twilight Zone produced some of the most enduring half hours in television history, along with a fair number of misfires.
Critics and fans rarely agree on a single ranking, but a clear pattern emerges once enough lists are stacked up against each other.
For an even more specific breakdown by mood, the show also has its own clear leaders for saddest, scariest, and most disturbing episodes.
The Best Episodes, According to Critics
A handful of episodes show up near the top of nearly every major ranking, whether the list comes from Rolling Stone, IGN, TV Guide, or Collider.
“To Serve Man” is one of the most frequently cited best episodes of the entire series, largely thanks to its famous closing twist. Aliens arrive promising to solve humanity’s problems, and a cryptographer spends the whole episode racing to translate the title of their guidebook before the final, grim reveal that it is, in fact, a cookbook.
“Time Enough at Last” is another perennial favorite, and reportedly Rod Serling’s own personal pick among everything he wrote for the series. Burgess Meredith plays a bookish bank teller who survives a nuclear war only to find an entire library left standing, then loses his glasses before he can read a single page.
“The Monsters Are Due on Maple Street” regularly tops critics’ lists for a different reason.
A power outage and a rumor of alien visitors are all it takes for an ordinary suburban street to turn on each other, and the episode’s closing message about prejudice and suspicion still gets quoted as a warning today.
Rounding out the most consistently praised episodes are “Nightmare at 20,000 Feet,” starring William Shatner as a man recovering from a breakdown who is the only passenger who can see a creature tearing apart the wing of his plane, and “Eye of the Beholder,” a dystopian story about a woman awaiting the results of mandatory cosmetic surgery in a society that considers her beautiful face to be the deformed one.
“It’s a Good Life,” about a small town terrorized by a six year old with god-like powers, and “Living Doll,” featuring the murderous Talky Tina, also appear near the top of most major rankings.
None of these episodes would have come together without the show’s deep, mostly uncredited bench of actors filling out every scene around the stars.
The Worst Episodes, According to Critics
The show’s grueling production schedule, 156 episodes across five years, meant a handful of episodes inevitably missed the mark.
The exact bottom of the list shifts depending on who is doing the ranking and when, since IMDb user ratings change over time, but the same handful of names keep coming up.
“The Bard,” the hour long season four finale about a failed screenwriter who summons William Shakespeare through black magic to ghostwrite his scripts, is one of the most frequently named worst episodes of the series.
Critics have called its satire toothless and its comedy painfully unfunny, despite an early, scene-stealing turn from a young Burt Reynolds doing his best Marlon Brando impression.
Other episodes that regularly land near the bottom include “Cavender Is Coming,” a broad comedy starring Carol Burnett that was the only Twilight Zone episode ever aired with a laugh track, and “Sounds and Silences,” about a sound-obsessed man who is cursed with extreme noise sensitivity.
At various points, each of these has held the dubious title of IMDb’s lowest rated episode, which says less about any one episode and more about how rocky the show’s comedic outings tended to be compared to its dramatic ones.
Season two’s brief, network-mandated detour into videotaped episodes also draws consistent criticism. CBS pushed the production to shoot several episodes, including “Static” and “The Lateness of the Hour,” on video instead of film to cut costs, and the resulting flat, soap opera look is still considered one of the show’s lowest points visually, even when the writing held up.
What both ends of the list tend to agree on is this: The Twilight Zone was at its best when it stayed dramatic and unsettling, and at its weakest whenever it tried too hard to be funny.
