Mission Blue

Mission Blue is a love letter to the ocean and a manifesto for its survival. Sylvia Earle, a legendary oceanographer, argues passionately for marine protection while diving to breathtaking depths. Visually stunning and emotionally urgent, it's for anyone who cares about the planet—or just wants to witness the sublime beauty of a world most of us will never see.

Should you watch it?

Watch it if you are drawn to a single determined scientist's life told through patient ocean footage, and you don't mind a film that is openly rooting for its subject.

Skip it if you want a film with edge or complexity, since its environmental message is earnest and sometimes repeats itself.

What it asks of you: At ninety-four minutes, it is short and steady, mixing ocean footage with interview, gentle in tone rather than grim, and needing no prior knowledge.

My Octopus Teacher2020

A South African filmmaker forms a year-long relationship with an octopus in a kelp forest, creating intimate moments of cross-species understanding and profound reflections on connection and change.

But The pacing is meditative and slow; if you want drama or conventional narrative arc, you'll find it muted and occasionally meandering.

Chasing Coral2017

Underwater cinematography that's jaw-dropping, following scientists documenting coral bleaching in real time. It's urgent and visually spectacular, with genuine stakes and emotional weight.

But The reality it documents is depressing, and the film doesn't offer false comfort; some viewers find it more paralysing than galvanising.

Our Planet2019

David Attenborough narrates a sweeping, visually magnificent survey of Earth's ecosystems and how climate change is unraveling them. Each episode is a masterclass in nature filmmaking.

But The environmental message can feel heavy-handed, and the scope sometimes distances you from individual stories rather than deepening your connection to them.

The wildcard

Something you would not have found on your own.

Stalker1979

Both films treat the act of witnessing something larger than yourself—whether alien wilderness or the living ocean—as spiritually transformative and ethically binding. They ask what we owe to the mysteries we encounter.

Tarkovsky's science-fiction masterpiece about a journey into a mysterious zone. Slow, hypnotic, utterly committed to contemplation over action. It shares Mission Blue's sense of awe before the unknown, and its insistence that some things are worth protecting even when we don't fully understand them.

But At 163 minutes with minimal dialogue and philosophical pacing, it demands patience most viewers won't have. It's less a film than a test of surrender.

Blue Planet II2017

Attenborough again, but focused entirely on oceans—revealing creatures and behaviours never before filmed. It's revelatory in scale and beautifully shot, with practical conservation angles woven throughout.

But Like all BBC natural history, it's vast and occasionally abstract; you won't follow characters across episodes, which some find emotionally cooling.

The Cove2009

A gripping investigative doc that exposes dolphin-hunting practices in Japan. Perfectly paced, morally coherent, and genuinely suspenseful—it changed real policy and real practices.

But It's confrontational in ways some find preachy; the filmmakers' righteousness may feel like an obstacle rather than an invitation to join them.

Blackfish2013

An exposé of SeaWorld's practices around orca captivity, structured as a mystery that gradually reveals something darker. Compelling narrative filmmaking in the service of a cause.

But It's manipulative in its framing, selecting interview subjects and moments to guide you toward one conclusion; more activist tract than balanced investigation.

David Attenborough: A Life on Our Planet2020

David Attenborough's personal reflection on decades of witnessing environmental decline, moving from archive footage to urgent calls for action. It feels like wisdom earned through witnessing.

But The structure is essentially a highlight reel of destruction followed by hope—it can feel like environmental TED Talk rather than deep exploration.

Seaspiracy2021

A fast-paced investigation into industrial fishing, with revelations that will shift how you think about 'sustainable seafood.' Accessible and genuinely eye-opening.

But It simplifies complex economics and sometimes cherry-picks sources; some criticise it for trading nuance for viral urgency and engagement.
