The best David Attenborough documentaries, ranked by the numbers

Sir David Attenborough turned 100 on 8 May 2026, a milestone only a tiny fraction of people ever reach, and none of them with a back catalogue that has redefined how an entire species understands its own planet. LEGO marked the occasion by updating its classic “4-99” age label to “4-100+” in a birthday tribute post, with the line “There’s no age limit for those who never stop playing.” It is a good line, and a good excuse.

Rather than another opinion-led list of his best work, this one asks a different question: what do the numbers actually say? We pulled IMDb audience scores, Metacritic critic scores where available, and box office data for his most recent release, and the results are genuinely interesting. Some of the obvious picks are obviously great. Others are rated just as highly and almost never mentioned. A few surprises sit right at the top.

How we ranked them

Three simple, consistent sources: IMDb audience rating, Metacritic score where available, and box office or viewership data where relevant. Almost all of Attenborough’s major series cluster between 8.5 and 9.5 on IMDb, which makes the small gaps meaningful. A 9.4 versus a 9.0 across hundreds of thousands of votes is not noise; it is a genuine signal.

The results split naturally into three tiers: the series that earn every word of the hype, the modern experiments that over-deliver, and the underrated heavyweights that rate almost identically to Planet Earth but rarely make anyone’s top five.

Tier 1: The series that earn the hype

Ocean with David Attenborough (2025)

Start here because it is the newest, and because the numbers behind it are remarkable for a documentary. Ocean arrived in cinemas on 8 May 2025, coinciding with Attenborough’s 99th birthday, and became the highest-grossing documentary release of 2025 in the UK and Ireland, as well as the highest-grossing nature documentary in cinemas this decade. It is now on Disney+. The film covers coral reefs, kelp forests and open ocean, and lands closer to a rallying cry than a traditional nature series. Surprisingly hopeful for something built around urgency.

Planet Earth (2006)

The one that most people think of first, and the numbers back that instinct up. Planet Earth sits at 9.4 out of 10 on IMDb from around 235,000 votes, making it one of the highest-rated television series on the entire platform, not just within the nature genre. That is not a niche audience giving it a pass; it is a genuine mass consensus. If someone asks where to start, this is always the right answer, and the data agrees.

Blue Planet II (2017)

By critic consensus, this is arguably the best-reviewed series Attenborough has ever made. Blue Planet II holds a Metascore of 97 on Metacritic alongside a 9.3 out of 10 on IMDb. The underwater cinematography is unbelievable in places, and the plastic pollution episodes were widely credited with shifting public behaviour around single-use plastic in a way that campaigns alone never managed. If Planet Earth has the cultural weight, Blue Planet II has the critical consensus.

Planet Earth II (2016)

Ten years after the original and somehow even more impressive technically. Planet Earth II holds a Metacritic score of 96 alongside a 9-plus IMDb rating, meaning both critics and audiences rate it ahead of almost everything else in the genre. The baby iguana and snake sequence became one of the most watched nature clips in television history. The Cities episode alone is worth the watch.

The Blue Planet (2001)

Before the original Blue Planet, the ocean felt unknowable on screen. It holds a 9.0 on IMDb and is regularly cited by the BBC and others as the series that changed how ocean documentaries were made. The sequel may have surpassed it on critic scores, but the original set the template for everything that followed.

Our Planet (2019)

Our Planet sits at 9.2 out of 10 on IMDb, putting it right in the conversation with the very best of his work. It marked Attenborough’s arrival on Netflix and brought a harder environmental edge than most BBC productions. The walrus cliff sequence became infamous, sparking genuine debate about how nature documentaries handle difficult footage. Available on Netflix Ireland.

Seven Worlds, One Planet (2019)

Here is where the data starts to tell you something the casual conversation around Attenborough’s work does not. Seven Worlds, One Planet holds a 9.3 out of 10 on IMDb, statistically right alongside Blue Planet II and Planet Earth II, and yet it almost never makes anyone’s shortlist. It structures its seven episodes around the continents, and the Antarctica episode in particular is exceptional. This is one of the clearest gaps between the numbers and the cultural memory.

Frozen Planet (2011)

Frozen Planet sits at 9.0 on IMDb and is frequently singled out as the definitive record of the polar regions before rapid climate change began to alter them permanently. The sense of scale, ice shelves collapsing, polar bears navigating sea ice, migration across frozen tundra, gives it a weight that the broader ecosystem series do not always match. Available on BBC iPlayer and Netflix Ireland.

Life on Earth (1979)

Everything starts here. Life on Earth is more than four decades old and it shows in the production values, but context matters enormously. This was the series that defined what a nature documentary could be, that planted the techniques, the camera patience, the visual storytelling, that everything above is built on. It still appears consistently in BBC and anniversary best-of lists precisely because without it, none of the rest exists.

Tier 2: Modern experiments that over-deliver

Prehistoric Planet (2022)

The most surprising entry on this list by some margin. Prehistoric Planet uses photorealistic CGI to put Attenborough in a nature documentary about dinosaurs, and it holds an 8.4 out of 10 on IMDb, which is unusually high for fully effects-driven work. Reviewers consistently highlight how naturalistic it feels. The technology has reached the point where you forget you are watching rendered creatures. The first two series, narrated by Attenborough, are exclusive to Apple TV+.

Wild Isles (2023)

This one deserves more attention from Irish audiences specifically. Wild Isles holds an 8.6 on IMDb and is the only major Attenborough series to spend serious time on British and Irish ecosystems, puffins, otters, killer whales off the Scottish coast. It is a quieter series than Planet Earth, and that is exactly what makes it worth watching. Available on BBC iPlayer and Amazon Prime Video Ireland.

Life in Colour (2021)

An 8.2 on IMDb for a three-part concept series built entirely around colour vision is solid. It is unusually focused compared to the sprawling ecosystem epics, which means it works better than it might sound, and it covers territory none of the bigger series bother with. Worth a look if you have worked through the obvious ones.

Tier 3: Underrated heavyweights

Dynasties (2018)

The most striking gap between rating and reputation on this entire list. Dynasties holds a 9.1 out of 10 on IMDb, putting it in essentially the same bracket as Planet Earth II and Our Planet. And yet it almost never appears in casual top-five lists. It follows individual animals over time rather than surveying ecosystems, five episodes, five species, and the chimpanzee episode in particular is extraordinary. If you have watched everything in Tier 1 and want to know what to watch next, this is the answer the data gives you.

Life (2009)

Life does not always surface with a clean IMDb number in the way some others do, but BBC and critic retrospectives consistently place it alongside Frozen Planet and Planet Earth at the very top of his output. It takes the Planet Earth format and pushes it further into animal behaviour, dedicating each of its ten episodes to a different group of species. Some of the predator and prey sequences are among the most extraordinary ever filmed. Available on BBC iPlayer and Netflix Ireland.

The Private Life of Plants (1995)

The data point that surprises people most. The Private Life of Plants holds a 9.0 on IMDb, more than holding its own against 4K productions made thirty years later. It uses time-lapse photography to reframe plant behaviour as something genuinely dramatic, and it works in a way that should not be possible for a mid-90s series about plants. Among Attenborough enthusiasts it is consistently cited as one of his finest pieces of work. Available on BBC iPlayer.

What the numbers actually tell you

The Tier 1 series are tier one for a reason. Planet Earth, Blue Planet II, Planet Earth II, Our Planet, all of them earn their reputation with both audiences and critics, and the IMDb scores reflect genuine consensus across hundreds of thousands of votes. The surprise is how close the rest are. Dynasties rates the same as Our Planet. Seven Worlds, One Planet rates the same as Blue Planet II. The Private Life of Plants, a thirty-year-old series about plants, sits level with Frozen Planet. The cultural conversation around Attenborough has a shortlist, and the data suggests it is too short.

One more thing worth adding. On his 100th birthday, the BBC confirmed that Blue Planet III is in the works and that Attenborough will return to narrate it. Retiring at 100 was apparently never under consideration.
