Netflix viewers are all agreed on the best documentary available on the streaming service

Fans of Netflix have revealed what they think is the best disturbing documentary available on the platform.

Looking for tips on what to watch on Netflix a fan posted to the Facebook group Netflix Bangers to ask for advice.

She asked fans to advise her about the "best documentary that will have me like wtf".

There's certainly no shortage of disturbing documentaries out there either, with plenty of options from true crime to investigations.

And people certainly poured into the comments to come out with a lot of suggestions.

One said Girl in the Picture, while another suggested Dear Zachery: A letter to a son about his Father.

A third even jokingly suggested the dystopian comedy Idiocracy.

But there was one which topped them all.

This was the highly disturbing documentary Don't F*ck With Cats, with many people piling into the comments to offer their agreement.

The three-part docuseries follows the hunt for Luka Magnotta after he murdered Lin Juan.

But why the title referring to cats?

That's because Magnotta, who was born in 1982 as Eric Kirk Newman, also posted videos of himself killing cats and kittens on the internet by suffocating or drowning them.

These included one instance where he filmed himself feeding a live cat to a snake.

Following these horrifying videos, internet sleuths were already on the lookout for Magnotta and were trying to track him down.

But things moved into a full criminal investigation when Magnotta's crimes escalated enormously.

That's because in 2012, Magnotta brutally murdered 33-year-old computer engineering student Lin Jun.

Echoing how he had previously posted online, Magnotta posted a video online which showed him killing Lin and then abusing his corpse.

This included dismembering Lin's body and mailing his hands and feet to the headquarters of the Liberal and Conservative Parties in Canada, as well as to two elementary schools.

Magnotta fled to Europe where he was eventually found in an internet cafe, where he had been reading news stories about his crimes.

Finally, in 2014 he was given a life sentence for Lin's murder.

People piled into the comments to share their thoughts on the documentary, with one writing that the movie "had me not wanting to watch but not being able to look away."

Meanwhile, another reflected on how disturbing it was, writing: "I still have intrusive thoughts from this movie. It’s pretty disturbing".

And someone else warned anyone who wants to see it, posting: "oh god!! Just be ready for this one. It’s sooo disturbing."
