Netflix Viewers Left Disgusted At Sneak Peek Of New True Crime Our Father

The documentary follows the story of disgraced former fertility doctor Donald Cline, who covertly inseminated female patients with his own sperm, fathering over 50 children in the process.

Watch the trailer here:

The story first broke in 2016 when one of the siblings reached out to a local radio station and since then the story of the half-siblings has been heard worldwide.

The teaser for the highly-anticipated documentary begins with a voice over, which says: "Growing up, I felt different. I was 35 and I take a DNA test."

The trailer then switches between some of the half-siblings as they detail how they discovered the truth through at-home DNA tests, with one saying: "When I opened Ancestry, I had over 3,000 hits."

The documentary appears to delve into Cline's possible motivations, with one of the siblings saying: "I think it was some sick experiment for him. Most of us have blonde hair, blue eyes. It was almost like this perfect Aryan clan. It's disgusting."

One emotional clip shows the mother of one of the children saying, "I had to tell my husband, 'we're just now finding out that Julie is not yours.'"

While the families affected continue to fight for some form of justice, the trailer reveals that unbelievably there is no crime that covers this act.

One clip details how the siblings live in dread of more being discovered, with one stressing the fear that it could be someone they already know, or even someone they dated.

Viewers reacted with shock to the trailer, taking to Twitter to express their disgust at Cline's actions.

One user described the case as "disgustingly fascinating..."

Another wrote: "Good grief this makes your skin crawl"

"'Truth is stranger than fiction ...'. Can say that again. This is horribly astonishing" Added a third.

"This new @netflix doc looks intense. I'll definitely be watching when it comes out." Wrote one fan. While others said they might give it a miss as "Just reading the headline of the article about the series makes me feel sick."

"OK this looks just crazy. How does this happen for so long?" Questioned one Twitter user.

Our Father drops on Netflix on Wednesday 11 May, 2022.
