10 Documentaries That Will Make You Angry

#10: “Abducted in Plain Sight” (2017)

If you want your blood to boil, look no further. What makes “Abducted in Plain Sight” so hard to watch is not just the nightmare at its center, but the sheer number of preventable mistakes surrounding the crime. The film chronicles how a family repeatedly trusted a manipulative predator, ignored obvious warning signs, and let him stay far too close to their daughter. Every new revelation is more maddening than the last, especially because the documentary makes it clear how easily avoidable it all was. While obviously the predator is ultimately to blame, it’s hard not to feel like everyone failed Jan Broberg.

#9: “The Inventor: Out for Blood in Silicon Valley” (2019)

With this, you might find yourself asking, "How did nobody stop this?" It’s a chilling look at the rise of Elizabeth Holmes and Theranos, a startup that promised to revolutionize blood testing. Investors poured in money, influential figures joined the board, and Holmes became one of America's most celebrated entrepreneurs. Despite concerns from scientists, former employees, and investigative reporters, the illusion persisted. Of course, startup failures are common, and investors losing money is part of the risk. But what makes this story so disturbing is the human cost. Patients received inaccurate test results, potentially affecting life-changing medical decisions. Perhaps the most maddening part is seeing Holmes channel that Steve Jobs charisma and showmanship while knowing all along that she was a fraud.

#8: “Wormwood” (2017)

Nothing is more frustrating than searching for answers and finding only more questions. That's the experience many viewers have with “Wormwood.” Director Errol Morris revisits the mysterious 1953 death of Frank Olson, a government scientist who fell from a New York hotel window. Officially ruled a self-inflicted death, the case became the subject of decades of speculation involving secret CIA experiments and possible cover-ups. At the center is Olson's son, Eric, who spent much of his life searching for the truth. The documentary presents itself as a gripping conspiracy thriller, but many viewers found its constant shift between documentary and dramatized reenactments confusing. Worse still, theories are revisited repeatedly, only for the story to end pretty much where it began: with no definitive answers.

#7: “Athlete A” (2020)

Some documentaries make you wonder how a scandal happened. “Athlete A” makes you question how it was allowed to continue for so long. The documentary paints a disturbing picture of institutions seemingly more concerned with protecting their reputations than safeguarding young athletes. It examines the abuse committed by former USA Gymnastics doctor Larry Nassar and the journalists who helped expose it. The survivors' accounts are difficult enough to hear, but what’s most frustrating is the repeated failure of those in authority to act. Athletes raised concerns, and warning signs emerged, yet the abuse continued for years. Nassar was eventually sentenced to over 300 years in prison, while USAG president Steve Penny was later indicted for tampering with evidence. But the consequences came decades too late.

#6: “The Keepers” (2017)

If "Athlete A" left you angry at an institution’s humongous failure and cover-ups, "The Keepers" will have you boiling over the sheer weight of what was buried. This docu-series begins with the 1969 murder of Sister Cathy Cesnik, a Baltimore nun whose killing remains unsolved. As the investigation unfolds, it expands into allegations of systematic abuse by Father Joseph Maskell, a school chaplain accused of assaulting at least 39 victims. Viewers are angered not only by the abuse described, but by the possibility that the Church helped keep it buried. Former students spent decades searching for answers, only to encounter more obstacles. Maskell fled to Ireland and died in 2001, having never been charged. No justice was attained in the end.

#5: “Predators” (2025)

For years, “To Catch a Predator” was must-see television. Millions tuned in to watch suspected predators walk into sting houses, only to be confronted on camera by journalist Chris Hansen. The show was initially praised, but ended in controversy. In 2025, director David Osit revisits the phenomenon in “Predators,” a documentary that peels back what was really happening behind the scenes. That’s where the discomfort begins. What may once have felt like a guilty pleasure now feels deeply uneasy in hindsight. The methods used to catch suspects, the use of teenage decoys in staged scenarios, and the loose regulatory standards of early reality television all come under scrutiny. Viewers are left torn between applauding the outcomes and questioning how they were achieved.

#4: “The Disappearance of Madeleine McCann” (2019)

One of the most famous missing-person cases in modern history still has no definitive answer. In 2007, young Madeleine McCann disappeared from a holiday apartment in Portugal, sparking a worldwide media frenzy. This Netflix documentary reexamines the investigation, the theories, and the years of speculation that followed. As if the tragedy itself isn’t harrowing enough, many viewers are confronted with an endless cycle of dead ends and unanswered questions. Suspects build up only to be cleared, including the parents themselves. The McCann family refused to participate and urged others to do the same. Critics called it exploitative and said it offered nothing new. By the end, audiences are left exactly where they started, with no answers or resolution.

#3: “Don't F**k with Cats: Hunting an Internet Killer” (2019)

Animal abuse. Internet detectives. Murder. Where do we even begin with this one? This heartbreaking documentary follows a group of online sleuths determined to identify a man posting disturbing videos of animal cruelty. Their search eventually leads them to Luka Magnotta, whose crimes escalate in shocking ways. The documentary is gripping, but it can also be incredibly frustrating. Viewers find themselves wondering why obvious warning signs weren't taken more seriously sooner. The online community repeatedly uncovers clues pointing directly at the suspect, while authorities struggle to catch up. But the deeper frustration sets in later. By platforming Magnotta so extensively, the documentary arguably gives him exactly what he wanted: notoriety. Viewers finish it feeling uncomfortably complicit in the spectacle they just watched.

#2: “Dear Zachary: A Letter to a Son About His Father” (2008)

A father’s touching letter to his son? This plays more like a grandparent’s worst nightmare. Filmmaker Kurt Kuenne originally created “Dear Zachary” to preserve the memory of his murdered friend Andrew Bagby for the son he never got to raise. What begins as a heartfelt tribute quickly turns into something far more devastating. Andrew’s suspected killer, Shirley Turner, was released on bail while awaiting trial and granted custody of baby Zachary. His grandparents fought desperately to protect him, but the courts ruled otherwise. The ending is harrowing, as Turner commits an unthinkable act just when a breakthrough seems close. How could a known murder suspect be entrusted with a child? It remains one of the most devastating documentaries ever made.

#1: “The Act of Killing” (2012)

Most documentaries about mass murder focus on the victims. "The Act of Killing" does the exact opposite. Joshua Oppenheimer's film turns to Indonesia's 1965 anti-communist purges, where paramilitary death squads killed hundreds of thousands. Instead of survivor testimony, the filmmakers ask former perpetrators to reenact their crimes in the style of Hollywood films. The men agree enthusiastically. They choreograph torture scenes, assign each other roles, and watch the playback with satisfaction. One perpetrator, Anwar Congo, dances on the rooftop where he killed people. Sadly, the killings were never punished. These men are free, celebrated, and socially respected. Even wilder, Oppenheimer had to resort to this unconventional approach because he had been initially threatened.
