The Norliss Tapes had several good things going for it: a interesting premise, Roy Thinnes in the lead role, an excellent and suspenseful soundtrack, beautiful sets and scenery (rural coast of northern California) but it failed to live up to it's potential and was cancelled after only a few episodes.
The premise had David Norliss investigating super-natural phenomena. However, the first episode featured an over-the-top maniac zombie on a killing-spree. This may have worked if the zombie was more mysterious and secretive, but instead, he was an in-your-face zombie. Instead of being frightening, he is slightly absurd and unbelievable.
Nevertheless, it is fun to watch David Norliss (Roy Thinnes) drive along the Pacific highway in his slick corvette and explore isolated mansions investigating the unknown. And there is always the lingering intrigue of what happened to David Norliss himself, because the story is told in flashbacks as his publisher plays the audio tapes left behind by the now-missing Norliss.
Hopefully, the remainder of the Norliss Tape episodes will be released on DVD so us 70's cult addicts can get another fix.
