As weird as it sounds, “I Am Not a Serial Killer” feels like a “Back to the Future” episode gone horribly wrong, proffering a twisted, satanic version of the Doc-Marty relationship.
Doc (Christopher Lloyd), the older mentor, and Marty (Michael J. Fox), the teenage protege, were a little crazy, but they were fun to be around and their rapport and friendship warmed our hearts. In 1989’s “Back to the Future 2,” the pair traveled to 2015 only to discover that the world had turned bad and dark (but with cars that can fly). They tried to fix things up and bungled some stuff, but ultimately they succeeded in turning the tables on fate.
