Neat but too preach! Valley of the Shadow starts out strong. A dog chases a cat starts out a chain of events. The town is a machine which can change time and people. The reporter investigates and a interesting story unfolds. The town guards the secret. Great episode until the bottom quarter. The reporter character flips out, understand the wip out to a point, but goes way too nuts. The reporter shoots several towns people to show the Rod Serling narrative how evil modern society is. Did not mind it. Goodending of time being changed at the ending. Interesting, but over the top social message. 6 out of 10 stars.
