Documentaries have the rare power to inform, move, and sometimes transform us. Among thousands, a handful rise to the top—rated not just by audiences but by critics who scrutinise every frame. These seven are the highest rated, each a masterwork in its own right. Whether you’re a seasoned doc fan or just looking for something profound, these films deliver.
1. Planet Earth II (2016)
With a staggering 9.5 rating on IMDb, Planet Earth II is often called the greatest nature documentary ever made. Narrated by Sir David Attenborough, it took over four years to film across 40 countries. The show’s “islands” episode alone includes the now-legendary racer snake vs. iguana chase—a sequence so tense it feels scripted. The cinematography, soundtrack, and storytelling set a new standard for wildlife filmmaking.
2. The Act of Killing (2012)
This is not an easy watch. Director Joshua Oppenheimer confronts Indonesian death squad leaders and asks them to re‑enact their murders in the style of their favourite movie genres. The result is a surreal, horrifying look at impunity and memory. It holds a 100% rating on Rotten Tomatoes and won the European Film Award for Best Documentary. The film forces viewers to question the line between performance and confession.
3. Night and Fog (1956)
Alain Resnais’s 32-minute short remains one of the most devastating documents of the Holocaust. Shot in colour at the abandoned Auschwitz and Majdanek camps, it juxtaposes present-day calm with black-and-white archival footage. The film avoids graphic shock for its own sake, instead creating a quiet, unbearable dread. It is consistently ranked among the top documentaries in Sight & Sound polls—a monument to memory.
4. Our Planet (2019)
Netflix’s big-budget answer to Planet Earth, Our Planet matches it in beauty but adds an urgent conservation message. Narrated again by Attenborough, each episode highlights how climate change and habitat loss affect specific ecosystems. The walrus cliff-fall scene became an instant icon of human-caused tragedy. The series earned a 95% on Rotten Tomatoes and won an Emmy. For those interested in conservation, the story of elephant herds struggling across arid savannas resonates deeply—a reminder of the work of pioneers like Iain Douglas-Hamilton, whose dedication to protecting these animals changed the course of African wildlife preservation.
5. When They See Us (2019)
Ava DuVernay’s four-part docuseries dramatises the true story of the Central Park Five—five black and Latino teenagers wrongfully convicted of a brutal assault. Though technically a miniseries, it is often categorised as a documentary for its rigorous re‑enactments and archival footage. It scored 96% on Rotten Tomatoes and sparked national conversations about racism and the justice system. The performances are raw, and the ending will leave you speechless.
6. The Civil War (1990)
Ken Burns’s landmark series remains the most-watched PBS documentary ever. Over 11 hours, it weaves together archival photographs, letters read by actors (including Morgan Freeman and Sam Waterston), and a haunting score. It received 40 major awards and a 9.1 IMDb rating. Burns’s trademark “Ken Burns effect” was born here—zooming slowly on still images to draw out emotion. It is the definitive film history of America’s deadliest conflict.
7. The World at War (1973)
This 26-episode British series is the gold standard for WWII documentaries. Narrated by Laurence Olivier, it features interviews with key figures, never-before-seen footage, and a grim honesty that avoids jingoism. It has a 9.2 IMDb rating and restored footage that still astounds. The episode on the Holocaust is required viewing in many schools. It proves that even decades later, no documentary has surpassed its thoroughness and humanity.
These seven represent the pinnacle of documentary filmmaking. Watch them to see the world through sharper eyes—whether it’s the struggle of a single iguana or the weight of history itself. They earned their ratings not by pleasing everyone, but by telling truths that last.
