âThe Night Stalkerâ AKA âKolchak: The Night Stalkerâ is a seminal show that has lead to an entire subgenre of entertainment, âThe Paranormal Investigator.â From âScooby Dooâ to âSupernaturalâ (and beyond), the paranormal investigator came to prominence with âThe X-Filesâ but this show and many others owe a debt to the man in the blue suit, Carl Kolchak.
