HUMAN
Watch HUMAN on YouTube
Some documentaries tell you about people. HUMAN lets people tell you about themselves. There’s no narration guiding you, no expert cutting in to explain what you’re hearing. Just one person after another, speaking directly to the camera, sharing truths they’ve carried their whole lives.
Director Yann Arthus-Bertrand interviewed hundreds of people from across the globe: farmers, refugees, prisoners, CEOs, students. They speak about love, loss, injustice, joy, and small moments that shaped their lives. Between these conversations, the film cuts to sweeping aerial shots of deserts, oceans, bustling cities, and open plains. It’s a visual reminder of the shared world these stories come from.
The pace is unhurried, giving you space to absorb each thought. By the end, certain faces and voices will stay with you, almost like you met them in real life.
The full multi-hour cut is available for free on YouTube. Watch it when you have time to sit with it, because it asks you to listen as much as you watch.

The Farthest: Voyager in Space
Watch The Farthest: Voyager in Space on PBS
Few documentaries capture the wonder of exploration quite like The Farthest. Produced by PBS, it tells the story of NASA’s Voyager missions—two spacecraft launched in 1977 that have since traveled farther than any other human-made objects.
The film blends stunning archival footage, interviews with the scientists and engineers who made it happen, and jaw-dropping images sent back from deep space. You’ll learn how these small, seemingly fragile machines carried the famous Golden Record, a message to any intelligent life that might encounter them.
What makes The Farthest so captivating is how it balances science with human emotion. It’s not just about the data collected; it’s about the sheer audacity of sending a piece of ourselves into the unknown. Whether you’re a space enthusiast or someone who just enjoys a good adventure story, this documentary will leave you with a renewed sense of awe for what humanity can achieve.

Chasing Coral
Watch Chasing Coral on YouTube
Chasing Coral is part detective story, part environmental wake-up call. The film follows a team of divers, scientists, and photographers on a mission to document the rapid disappearance of coral reefs around the world. What begins as a beautiful underwater journey soon becomes a race against time as warming oceans cause entire reef systems to bleach and die.
The visuals are breathtaking until you see the stark contrast after the damage sets in. Interviews and on-site footage explain the science in plain language, making the crisis understandable without diluting its urgency. It’s the kind of emotional punch you might not expect if you’re used to lighter fare like the feel-good movies we recommend, but it’s impossible to look away.
By the end, you can’t help but feel connected to these fragile ecosystems and the people fighting to protect them. If you’ve ever doubted the impact of climate change, Chasing Coral delivers the evidence in living color.

The Facebook Dilemma
Watch The Facebook Dilemma on YouTube
Imagine a thriller where the central figure isn’t a person but a platform. The Facebook Dilemma plays out with that same intensity.
Produced by PBS Frontline, this two-part investigation traces Facebook’s journey from a college networking site to a company capable of swaying elections and fueling political unrest. It unfolds carefully, layering insider interviews, clips from Mark Zuckerberg’s public statements, and detailed reporting that shows just how fast the company’s influence grew.
What makes it stand out is the way it connects the dots. Privacy scandals, the spread of misinformation, and political targeting—none are treated as isolated incidents. Instead, they’re shown as part of a larger pattern of decisions made in the name of rapid growth, often without anticipating the consequences.
The full documentary is available on YouTube and is as engrossing as some of the best true crime documentaries. It’s the kind of viewing that might leave you rethinking how you use social media and how much control you’re willing to give it over your digital life.

Ava DuVernay’s 13th is a must-watch for anyone curious about how history shapes today’s world.

Using a mix of archival footage, interviews, and striking visuals, it uncovers connections between policy, politics, and systemic inequality.
What makes 13th compelling is how it balances information with storytelling. You’re not just reading statistics—you see real people affected by laws and systems, and you understand the broader social forces at play. It’s sharp, emotional, and eye-opening, yet presented in a way that’s easy for a beginner to follow.
Even though the topic is heavy, the documentary is gripping from start to finish. It’s the kind of film that sparks conversation long after the credits roll. And the best part?

Watch The Internet’s Own Boy: The Story of Aaron Swartz on Internet Archive

The Internet’s Own Boy follows Aaron Swartz from teenage prodigy to outspoken activist, and then into a legal battle that changed how many people view access to information. The director arranges the story like a tight biopic, using archival footage, Aaron’s own words, and interviews with friends and family to build a clear portrait of who he was and what he stood for.
Technically, the film is economical and sharp. Editing keeps the momentum moving even as the subject matter grows heavier. The score never overwhelms the interviews. Cinematically, it balances moments of triumph with scenes that feel quietly devastating. You will find yourself rooting for the practical idealist on screen, and also asking tough questions about laws, institutions, and how societies treat dissent.

If a machine could outthink you, outplan you, and even outmaneuver humanity, would you still build it?
Do You Trust This Computer? invites you to sit with that question while showing how artificial intelligence is shaping the world right now. There are self-driving cars moving through busy streets, algorithms anticipating your choices before you make them, and robots learning skills at a pace that feels almost unnatural. It unfolds like a sci-fi story, except every scene is real.
The film balances possibility with caution. Experts from science, technology, and business speak frankly about the opportunities and risks that come with smarter machines. The future they describe feels both inspiring and unsettling.

Enron: The Smartest Guys in the Room
Watch Enron: The Smartest Guys in the Room on YouTube
Some corporate scandals make headlines and fade away. Enron’s collapse is the kind you never forget once you know the details.
This documentary pulls you inside one of the biggest business frauds in history. It shows how a company that once symbolized innovation and wealth became a cautionary tale about greed, arrogance, and deception.
You meet the executives who crafted the illusion, the employees who got caught in the middle, and the journalists who started asking questions when the numbers stopped making sense.
The pacing is sharp. It moves from glossy corporate events to tense boardroom decisions, then to the chaos that followed when everything fell apart. The interviews are blunt, and the archival footage captures an era when Wall Street felt untouchable.
It is available for free on YouTube, and it is worth watching if you want to see how ambition without accountability can take down more than just a company.

The True Cost
Watch True Cost on YouTube
Fashion might seem glamorous, but The True Cost peels back the curtain to show the hidden price of cheap clothing. This documentary examines the fast fashion industry—from the factory floors in developing countries to the overflowing landfills where discarded garments end up.
Through interviews with garment workers, factory owners, environmentalists, and designers, it connects the dots between low prices, poor labor conditions, and environmental degradation. The film is unflinching in showing the human toll, yet it’s accessible enough for viewers who’ve never thought about where their clothes come from.
What makes The True Cost stand out is its emotional impact. You see the real people behind the clothing tags, and you start to question whether a “good deal” is really good at all. It’s a sobering but necessary watch for anyone who’s ever shopped a sale rack without thinking twice. You can balance this with lighter viewing from our list of comfort shows to binge when life gets overwhelming.
