Paramount’s engrossing new drama series Happy Faceis inspired by the murders of the real-life Happy Face Killer, Keith Hunter Jesperson, but the series is not necessarily striving for point-by-point accuracy. The series focuses on his daughter Melissa, and the impact that his horrific crimes had on the lives of her, her loved ones, his victims, and their families. The show is based off the real autobiography and subsequent podcast of Jesperson’s actual daughter, Melissa Moore, so there are plenty of first-hand details littered throughout the show’s steadily-progressing plot.
