The Man in the High Castle is an American alternate history television series produced by Amazon Studios. The series is based on the 1962 novel of the same name by American science fiction author Philip K. Dick. The story is an alternate historyof the world in which the Axis powers won World War II. The United States has been divided into three parts: The Japanese puppet state of the Pacific States of America, which comprises the former United States west of the Rocky Mountains; a German puppet state that comprises the eastern half of the former United States; and a neutral zone that acts as a buffer between the two areas, called the Rocky Mountain States.
The pilot debuted on January 15, 2015 and as a pilot was Amazon's "most-watched since the original series development program began." On February 18, 2015, it was announced that it has been picked up for a season of 10 episodes to be released November 20, 2015.
I watched the first episode and it was actually quite good.
