Netflix Faces Backlash As Their Creative Decision Made The Lucy Letby Documentary Hard To Watch

On February 4, Netflix released a documentary about the infamous Lucy Letby. Soon after, it started to get a lot of buzz on social media, but not for the reasons Netflix was expecting. Apparently, to preserve the witnesses' identities, the streaming giant chose an unorthodox method.

They didn't use the usual tricks: altering the voices of the witnesses, shadowing them out, or using actors instead of the actual people. No, Netflix chose to digitally anonymize them by using AI. This decision caused an uproar on social media, with many people criticizing how uncanny, fake, and distracting the AI "actors" were.

Some people dubbed the "digital anonymization" "distracting" and "inauthentic"

Lucy Letby is a former neonatal nurse who worked at the Countess of Chester Hospital in the UK. In 2023, the authorities convicted her of taking the lives of seven babies and attempting to do it to seven more in 2015 and 2016. Currently, she is serving 15 life sentences in Bronzefield Prison in Ashford, Middlesex.

As the 2023 investigation showed, Letby injected air into the babies' bloodstreams or via their nasogastric tubes. The Netflix documentary includes interviews with one of the victims' mothers, "Sarah," and a former friend of Letby's who studied nursing with her at the University of Chester.

Netflix did warn the viewers that some people's faces would be altered, putting a disclaimer at the very beginning of the documentary. "Some contributors have been digitally disguised to maintain anonymity. Their names, appearances, and voices have been altered. Baby Zoe's real name has been changed to protect her identity."

However, once people saw exactly how Netflix did the digital alteration, some started questioning why they couldn't just use good old-fashioned methods: shadowing or blurring out the interviewees, changing their voices with audio engineering, or even hiring voice actors.

People complained that the uncanny valley vibe of the interviews really took them out of the moment. "It looks terrible. It's distracting," one Reddit user wrote. "Seeing someone whose hair doesn't move. Looks like a cartoon character. As someone else said, [I'd] rather just look at a black silhouette. It's a wasteful use of technology and energy and shows a lack of creativity. It feels inauthentic."

"It's disgusting and cheap," another added. "Why are you okay with the use of AI for such a sensitive story when they could've very easily hired a reenactment actress instead? They certainly could've afforded it."

But others think using AI "actors" might result in viewers becoming more emotionally involved

However, some people saw the other side of the coin of using AI to preserve people's anonymity in documentaries. They argued that the AI interviewees, on the contrary, bring more authenticity. Not everyone felt the disconnect that artificial intelligence creates, even though they could tell the expressions and body language were not natural.

"I believe it's to keep the protected person warmer and neutral than a blurred or silhouetted figure would feel," another commenter on Reddit wrote. "I am not saying I liked it but I kind of get it."

With blurred faces and obviously fake audio-engineered voices, people don't see the emotion on the interviewee's face. Some people say that it takes them out of the moment, and seeing the AI "actors" emote like real people keeps the human emotion in the documentary while preserving the anonymity and identity of the victims and the witnesses.

"Humans are influenced, both positively and negatively, by the facial expressions of one another," Charlotte Roberts, a writer for Grazia UK, argues. "In some ways, using AI puts a face to the story. We see eyebrows raise, foreheads furrow, and eyes grow teary as they tell their story. While the digital disguise on screen isn't real, the emotion is."

But that problem could've easily been solved by hiring actors. Using AI is, as Esquire's Matt Blake puts it, a disrespectful way to use special effects. "Grief is not something we just hear; we recognise it instinctively in another human face. In their eyes, their body language," he argues.

"Even an actor would have been one human's interpretation of another human's experience. Better, frankly, to deny us the image entirely – anything but turning their grief into a visual effect."
