Over at the Mike's Comments, we analyze one of the most popular episodes of the iconic Twilight Zone TV series. Besides being one of Rod Serling's personal favorites, this pic is unique in other ways.
For one thing, biting social commentary that hits very close to home, and does not favor the designated victim group du jour is generally not attempted, and when it does appear, is usually ignored. A few examples would be Over the Edge (1979); Meeting Evil (2012); and Unthinkable (2010). But, "Willoughby" was always popular. For another, the twist ending was very "meta" for its day, and the irony as well as the pun inherent in the title is--as they say in New England--wicked.
