True crime fans are struggling to get through a five-part documentary series that has been branded one of the most "disturbing" ever made. Born Evil: The Serial Killer and the Saviour, available on HBO Max and Now TV in the UK, explores the crimes of American killer Hadden Clark, who was convicted of multiple murders, including the killing of a six-year-old.
Originally released in the US in 2024 on Investigation Discovery, the series also covers Clark's behaviour in prison, where "horrific truths" emerge, and is said to be full of twists and turns.
Series synopsis
The official synopsis reads: "The volatile Clark family's inner workings, Hadden's depraved path, and his shocking confessions to a cellmate spur investigators to probe alleged cold case links."
Viewer reaction
A true crime fan on TikTok, who recently discovered the show, said in a video: "This is hands down the most disturbing true crime documentary series that I have ever seen and I have seen a lot."
Describing it as being about the "most disturbing and dangerous serial killer that you have probably never even heard of," the fan added: "I can't tell you how many twists and turns this documentary takes."
One commenter responded: "This was insane," while another wrote: "I have watched every true crime documentary going but after 3 minutes I had to turn this off it was so creepy."
What IMDb reviewers say
On IMDb, one reviewer said: "Everyone in my true crime groups are raving about the series as well. Many of us binged the whole 5 episodes already."
Another review stated: "It takes the first episode and into the second before you can't stop watching. Once the killers are introduced you may as well get the popcorn and settle in for a binge night."
A third praised the approach: "FINALLY! Finally a different directing style for a true crime show.! I watch so many and so many are the same and same criminals with no new information. This is a serial killer who I was not familiar with and much deeper dive into the family of the criminal."
Born Evil: The Serial Killer and the Saviour can be streamed on HBO Max and Now TV in the UK.
