An early example of the serial killer features that would eventually proliferate, "Killer's Delight" takes its inspiration (apparently) from the crimes of the notorious real-life Ted Bundy. A disguise-happy creep (John Karlen, 'Dark Shadows') rides about in a yellow van and regularly abducts, tortures, and slaughters attractive young women. A police detective named DeCarlo (James Luisi, "The Hidden") realizes that these murders are the work of one person, and is coldly determined to stop him, no matter what he has to do.
"Killer's Delight" (also known as "The Sport Killer" and "The Dark Ride") goes through its exploitative paces adequately, with suspense, titillation, and very little in the way of gore. Here, screenwriter Maralyn Thoma and director Jeremy Hoenack try to maintain a balance between following the actions of the psycho, and the actions of the cop. It has time for some humor, as DeCarlo pals around with fellow detective Mike Mitelman (Martin Speer (Wes Cravens' "The Hills Have Eyes"), who was also the art director on this show). The film is sufficiently entertaining, if not exemplary in any way. Its biggest plot twist occurs in the final third when DeCarlo asks his paramour, psychiatrist Carol Thompson (lovely TV veteran Susan Sullivan, 'Falcon Crest' and 'Dharma & Greg'), to act as the bait in a trap for the creep.
With other familiar faces like Hilarie Thompson ("Nighthawks"), Anne-Marie Martin (the original "Prom Night"), and Buck Flower ("They Live"), in a cameo as a distraught witness, it's easy enough to watch "Killer's Delight", especially as it works to create a constant sense of creeping dread. Karlen is a standout as the murderer, the kind of character one feels filthy just watching.
Overall, a decent procedural / body count thriller, somewhat obscure these days but which die hard fans of the genre may want to seek out.
