Burgess Meredith was one of the best guest stars on The Twilight Zone and his appearance in Time Enough at Last ensures this shows status as the best Twilight Zone episode of the entire series.

There is nothing more disturbing than Spock exhibiting emotion and in Plato's Stepchildren, he goes from laughing to crying to hatred and everything in between.

Sometimes, I can figure out the ending of a Twilight Zone episode within the first few minutes of the show. I thought that was the case here. But for some reason, King Nine Will Not Return fooled me with a slight plot twist at the end.
