YMMV / The Twilight Zone (1959) S5E3: "Nightmare at 20,000 Feet"

• Captain Obvious Reveal: Downplayed. Many viewers may be genuinely surprised to learn at the end that the gremlin was Real After All. Others might not realize they were ever supposed to think it was a hallucination in the first place (even aside from the It Was His Sled factor), due to the facts that 1) it's shown to genuinely move out of view whenever Bob tries to show it to someone else, 2) weird subhuman monsters are par for the course in the Twilight Zone, and 3) mental breakdowns don't produce hallucinations.
• Nightmare Retardant: The gremlin is just a guy with comically oversized lips, wrapped in a not-that-scary costume that amounts to little more than a human-shaped shag carpet. Honestly, the little girl's ventriloquist dummy looks way creepier. The movie remake version was genuinely scarier-looking.
• Signature Scene: Bob looking right out the window to find the gremlin staring right at him.
• Unintentional Period Piece:
  • Well fancy that, someone with a gun on an airplane, in plain sight. By 1983, the remade segment from The Movie had to justify the gun's presence onboard by having it concealed in an ankle holster by an FAA-authorized air marshal.
  • When Bob takes out a cigarette, his wife tells him to put it away... The plane hasn't taken off yet, after all.
• Values Resonance: Normally at the time, a character who'd recently been through something like a mental breakdown would've been female by default. The episode is also extremely sympathetic to Bob's struggles in general, treating him as a normal person and his breakdown as nothing to be ashamed of.
