Television often tends to lend more range and depth to its characters due to its long runtime. While there are a few films that have birthed memorable characters, television has richer characters since they get a lot more footage when compared to their counterparts in films. While television has gifted us with a lot of happy-go-lucky characters, seeing the bright side of everything life has to offer, it is also responsible for some of the most terrifying serial killers that at first glance look deceptively docile, but as the show progresses bloom into first-degree torture artists. Here are some of TV’s most terrifying serial killers, ranked.
