Athlete A

While there’s no repairing the damage done on dozens if not hundreds of athletes over the years by former USA Gymnastics doctor Larry Nassar, Athlete A offers many of those he victimized an opportunity to tell their story and expose the truth depths of his horrific crimes. It’s a heartbreaking watch at times but an important one, empowering the women previously in his care and proving that the truth will always come out.

Seaspiracy

You’ve probably heard loads of people saying they’ll never eat seafood again after watching Seaspiracy, and with good reason. This 2021 documentary delves into the environmental impact of mass fishing and highlights the damage and destruction caused on marine life by human beings. While there’s obviously a certain level of propaganda involved — Seaspiracy’s underlying message is about ending fish consumption — it makes some convincing arguments for why doing so might be a very good idea.

American Murder: The Family Next Door

Sadly, domestic violence and even murder between romantic partners isn’t all that uncommon, so the fact that Chris Watts killed his wife Shannan believing it would enable him to move on with his mistress is depressing but not all that surprising. Where this story does take a turn for the incredible, however, is when we learn that not only was Shannan pregnant, meaning Chris killed his unborn child, but that he also killed his two young daughters as well. American Murder: The Family Next Door tells the story of their tragic deaths as well as the web of lies and deceit Chris Watts weaved in an attempt to get away with it. It’s harrowing to say the least.

The Social Dilemma 

With a seeming-majority of society spending more time on phones than connecting with people face-to-face, it’s important to take a critical look at modern socio-interactive implications. The Social Dilemma interviews a variety of tech experts who expose plenty of industry secrets, many of which aren’t all that well-kept to begin with. However, this is one of the best Netflix documentaries because its discussion about the harm social media is doing to us as individuals and as a collective human race is posed with nuance and will certainly leave viewers with food for thought.

Abducted in Plain Sight

When 12-year-old Jan Broberg was abducted in 1974 by a close family friend, her family and wider community were incredibly relieved when she was eventually returned safely. Then the same man, Robert Berchtold, kidnapped Broberg again, leaving many wondering how on earth such a crime could have been allowed to happen once, let alone twice. Abducted in Plain Sight has many moments that will make you wonder what on earth people are thinking, as much of the story beggars belief. However, that’s part of what makes this one one of the best Netflix documentaries.

Sophie: A Murder In West Cork

If you’re a fan of dark, moody murder mysteries, this one is for you. A French woman who visited her holiday home in West Cork, Ireland over the Christmas holidays in 1996 was murdered, her dead body left on the rocky path leading to her secluded property. To this day, no one has been convicted for the murder of Sophie Toscan du Plantier. That is unless you count Ian Bailey, a local journalist who was sentenced to 25 years for the crime in France, but has avoided extradition.

My Octopus Teacher

Octopuses may not seem like the most exciting or endearing animals, but in this 2020 documentary, filmmaker Craig Foster manages to paint them in a much more flattering light. The winner of Best Documentary Feature at the 93rd Academy Awards, My Octopus Teacher follows Foster as he forms a relationship with a wild common octopus while diving in a South African kelp forest. The pair meet by chance but Foster soon begins following her around for close to a year, observing her throughout the ups and downs of her life.

Pray Away

Former leaders from the “pray the gay away” movement, begun by evangelical group Exodus International, talk about their departure from the church in this heartbreaking, and at times infuriating, documentary. Survivors of conversion therapy are also interviewed, giving them a platform to tell the horrors of the practice while being shown compassion for what they’ve been through. It’s hard to believe that barbaric practices like this are still happening in the world, but the more they’re brought to light, the closer we’ll be to eradicating them altogether, we can only hope.

Making a Murderer

Without a doubt one of Netflix’s most popular documentary offerings is Making A Murderer. It focuses on the case of Steven Avery, a Wisconsin man who was on the cusp of receiving a massive payout from Manitowoc County after spending 18 years in prison for a crime he didn’t commit. Right before he got his check, he was arrested and charged with the murder of Teresa Halbach, a photographer who had visited the Avery salvage yard on the day she was killed. Over a period of two seasons, the inconsistencies and horrible injustices faced by Avery and his nephew, Brendan Dassey, are explored and exposed, and while there’s no happy ending in sight for those involved, it’s an engrossing story you won’t be able to stop thinking about.

While many of the realities of the devastation and destruction we’ve brought about are sad and even depressing to think about, Attenborough’s intention here isn’t to bring viewers down.

How to Become a Tyrant

While we may assume that dictators like Adolf Hitler, Saddam Hussein, and Joseph Stalin would never come to power in the 21st century, the truth is that abuses of power are as widespread as ever and we’re only ever a few steps away from repeating the past. In How to Become a Tyrant, narrator Peter Dinklage explains how deep down, everyone wants absolute power and explores the ways in which individuals who are bold or simply unhinged enough can go about trying to get it. It’s slightly terrifying to delve into the stories of some of the world’s most notorious dictators, but well-worth the existential dread watching it may cause.

Elize Matsunaga: Once Upon A Crime

13th

Ava DuVernay’s 2016 documentary delves into America’s prison-industrial complex and how it disproportionately affects African-Americans. To illustrate and better understand this harsh reality, she explores the “intersection of race, justice, and mass incarceration in the United States” in very matter-of-fact terms, not shying away from the ugly truth of the country’s long-standing and continuing problem with racism. It can be hard and even uncomfortable to watch at times, which is all the more reason it needs to be.

Killer Ratings

Would a television producer and politician order murders to increase ratings for his TV show? Surely not, right? And yet, that’s exactly what many alleged Brazilian Wallace Souza was guilty of doing for more than a decade. The success of his Canal Livre show was largely based on Souza somehow managing to catch and “out” notorious criminals and even allowed him to be elected to public office, but not all was what it seemed. Killer Ratings exposes what just might be one of the most nefarious cover-ups in Brazil’s recent history.

While he’s now in prison after he created an explosive device that killed two people, the journey there is full of twists and turns that make this an interesting watch even for those who are entirely unfamiliar with the Mormon faith.
