Episode number five "Walking Distance" would be my favourite episode of The Twilight Zone. It is also one of the most popular and highly acclaimed of all Twilight Zone episodes and it was Rod Serling’s most personal story.
The acting, directing, music score, atmosphere and writing are all top notch in this episode and there are many great and unforgettable scenes. The wonderful and quite powerful scenes of Martin giving the childhood speech at the merry-go-round and Martin having his last ever conversation with his dad would be my favourites.
In Serling’s hometown of Binghamton, New York, there is even a plaque located in the Recreation Park bandstand that commemorates this fantastic episode. Binghamton’s Recreation Park was the inspiration for the park which features in Walking Distance and there is a very memorable scene that takes place there.
