Netflix synopsis: Single mother Liz falls for Ted Bundy and refuses to believe the truth about his crimes for years. A drama based on a true story. Rotten Tomatoes critic score: 54%Based in part on a memoir by Bundy's longtime girlfriend Elizabeth Kendall, Extremely Wicked, Shockingly Evil, and Vile follows the deranged killer (Efron) as he ingratiates himself into the life of Kendall and her young daughter, all while committing gruesome murders. Bundy kidnapped, raped and murdered some 30 women during the 1970s and possibly earlier.It's disturbing to see how easily Bundy was able to charm Kendall and her daughter into accepting him as part of the family, and even more terrifying considering the fact that Bundy once tried to kill Kendall. Most serial killer-centric films tend to focus on the murders or the efforts of law enforcement to catch the killer. And while Extremely Wicked doesn't shy away from portraying Bundy's grisly reign of terror, experiencing the crimes from a different perspective — that of Bundy's unwitting girlfriend — takes the terror to a whole new level. Netflix synopsis: Two journalists set out to get the definitive story of infamous serial killer Ted Bundy, as told by the man himself. Rotten Tomatoes critic score: 56%Extremely Wicked, Shockingly Evil, and Vile is a Hollywood retelling of Bundy and Kendall's story, but in Conversations with a Killer, viewers hear first-hand testimony from the murderer himself. The bulk of the docuseries is comprised of interviews Bundy did with journalist Stephen Michaud, as well as archival footage from Bundy's highly-publicized trials.For those who wonder how or why someone would want to take the life of another person, Bundy offers a partial, if disturbing, answer in Conversations with a Killer. Netflix synopsis: In 1977, frustrated FBI hostage negotiator Holden Ford finds an unlikely ally in veteran agent Bill Tench and begins studying a new class of murderer. Rotten Tomatoes critic score: 98%Serial killers aren't the main characters on Mindhunter — that honor would go to FBI Agents Holden Ford (Jonathan Groff) and Bill Tench (Holt McCallany) — but they do feature prominently in the Netflix drama. As Holden and Bill work to develop a better understanding of the minds of serial murderers, well known criminals such as Kemper, Manson, Berkowitz (the self-proclaimed Son of Sam killer) and Dennis Rader (the BTK Killer) all make appearances on the show.And even though the murderers don't have as much screen time as other characters, it's still chilling to see actors bring them to life — in all their cold-hearted violence. Netflix synopsis: Henry Lee Lucas rose to infamy when he confessed to hundreds of unsolved murders. This docuseries examines the truth — and the horrifying consequences. Rotten Tomatoes critic score: 100%Henry Lee Lucas killed three women — but confessed to the murders of many more.Once considered the most prolific serial killer in America, with his crimes spanning the 1960s to the 1980s, most of Lucas' confessions were later discredited through DNA or other evidence. While Lucas likely didn't have as many victims as other killers like Ted Bundy or Richard Ramirez, The Confession Killer shows how he was able to inflict terror in a different way. Netflix synopsis: Desperate to find her missing daughter, a mother fights to uncover the truth — and helps expose a string of unsolved murders. Based on a true story. Rotten Tomatoes critic score: 73%The Long Island Serial Killer, whose identity remains unknown, has been linked to the murders of ten people, mostly sex workers, in a remote area of Nassau County from 1996 to 2010 — and could potentially be involved in the disappearance and killings of dozens more. The cases were the focus of Robert Kolker's book Lost Girls: An Unsolved American Mystery, which later served as inspiration for this film. Focusing on Mari Gilbert (Amy Ryan) as she struggles to find out what happened to her daughter, Shannon, the film is a chilling and unforgettable examination of the Long Island Serial Killer's reign of terror.
