“The Night Stalker” AKA “Kolchak: The Night Stalker” is a seminal show that has lead to an entire subgenre of entertainment, “The Paranormal Investigator.” From “Scooby Doo” to “Supernatural” (and beyond), the paranormal investigator came to prominence with “The X-Files” but this show and many others owe a debt to the man in the blue suit, Carl Kolchak.
