A "contemporary prequel" to the 1960 film Psycho, depicting the life of Norman Bates and his mother Norma prior to the events portrayed in Hitchcock's film, albeit in a different fictional town and in a modern setting. The series begins after the death of Norma's husband, when she purchases a motel located in a coastal Oregon town so she and Norman can start a new life.
Unrelated, boring, ridiculous.
I don't understand how this non-existent story became so popular that it got its TV show. The "Based on an original movie Psycho from 1960" is just clickbait, this story has nothing to do with the movie except the names of characters and location. Most of the episodes are filled with absurdly stupid and unrealistic plot twists which make the whole show boring and unpleasant to watch. The most common question asked every few minutes was "why". There are more fictional TV series that are at least entertaining, this one is not. After the first few episodes, I treated it like a background for surfing the net and even then it was painful to finish the first season. I won't continue even if it's the last thing left to watch because it's not only a waste of time but also energy - both electric and mine.
