Lisa Johnson Mandell’s Avatar Fire and Ash review says this third installment shows what a master filmmaker can do when given full creative license.

James Cameron has proven that lightening can strike more than twice, but three times. With Avatar Fire and Ash, the visionary director proves that when it comes to pushing the boundaries of cinematic technology and storytelling craft, he remains at the top of his game, with few, if any equals.

This third journey to Pandora showcases the zenith of what modern filmmaking can achieve. Yet for all its breathtaking imagery and technical virtuosity, it’s not quite perfect, but close. The film stumbles at times under the weight of its own ambition, with a narrative that feels a little too familiar and, frankly, too long.

From the opening frames, Fire and Ash reminds us why IMAX screens and 3D technology were invented. Cameron’s world-building continues to astound, introducing us to the volcanic Ash People and their fierce leader Varang (Oona Chaplin), whose fire-wielding warriors bring a new dimension of danger to Pandora’s rich ecosystem.

The cinematography by Russell Carpenter is truly magnificent—every frame is meticulously composed, every movement purposeful. The bioluminescent forests we’ve come to love are joined by smoldering volcanic landscapes that glow with an ominous beauty, their orange and red hues contrasting starkly with the blues and greens that defined the previous films.

Avatar Fire and Ash review — Humanity rules

What truly sets this installment apart is Cameron’s steadfast commitment to authentic human performance. In an era where artificial intelligence threatens to upend traditional filmmaking, the director has been vocally adamant about his approach. “We don’t use generative AI,” Cameron declared at the Paris premiere. “We honor and celebrate actors. We don’t replace actors.”

This isn’t mere lip service—it took eighteen months to capture the performances for The Way of Water and Fire and Ash, with every nuance of the actors’ work preserved through performance capture technology. As Cameron explained to CBS Sunday Morning, the very idea of AI-generated characters is “horrifying to me. That’s the opposite. That’s exactly what we’re not doing.”

This dedication to the human element shows in the performances, which are uniformly excellent. The ensemble cast brings genuine emotional depth to their blue-skinned avatars, with Sam Worthington and Zoe Saldaña continuing to ground the franchise with their portrayal of grieving parents struggling to protect their family.

But it’s Jack Champion as Spider who truly emerges as this film’s beating heart. The young actor, who had to perform every scene twice—once in motion capture and again in live-action—delivers an engaging, layered performance that gives the film its most compelling emotional arc. Champion’s Spider wrestles with questions of identity and belonging in ways that resonate far beyond Pandora’s shores, and his work here deserves significant recognition.

One notable casting choice, however, raises questions. Sigourney Weaver’s 76-year-old voice portraying the teenage Kiri is not entirely convincing. While Weaver’s performance capture work allows her physical movements to read as youthful, her vocal performance occasionally betrays the character’s supposed age. Perhaps more sophisticated vocal effects or modulation should have been employed to better match the visual presentation. It’s a minor quibble in an otherwise stellar ensemble, but it’s noticeable enough to occasionally break the immersion Cameron worked so hard to create.

Avatar Fire and Ash review — not quite perfection, but what movie is?

Which brings us to the film’s most significant drawback: its running time. At 195 minutes, Fire and Ash is Cameron’s longest film to date, tied with Titanic. While the technical achievements and visual splendor justify some of this length, the narrative simply doesn’t warrant over three hours, and this Avatar Fire and Ash review is hardly the only one to notice this.

The plot—centering on the Sully family’s continued struggle against human invaders and now hostile Na’vi clans—feels too similar to its predecessor’s structure. We’ve seen this story before: capture, rescue, epic battle, repeat. Any story, no matter how grand, can and should be told in under three hours, and Fire and Ash proves this maxim with its meandering middle section.

Despite this significant flaw, Avatar: Fire and Ash stands as one of the best films of the year. Cameron’s technical mastery is matched by his ability to create moments of genuine emotional resonance, and Simon Franglen’s soaring score elevates the material.

The film’s late December release, however, may cost it the awards recognition it deserves. Many awards voters responsible for nominations and voting likely hadn’t had the opportunity to see it before deadlines passed, potentially robbing the film and its exceptional performances—particularly Champion’s breakthrough work—of the accolades they merit.

After all, Fire and Ash is a testament to what cinema can achieve when a master filmmaker insists on doing things the hard way, the human way. It’s too long, yes, and perhaps too familiar in its narrative beats. But when Pandora’s volcanoes erupt across a massive screen, when Champion’s Spider makes his pivotal choices, when Cameron’s camera soars through alien skies with the confidence of a director who knows exactly what he’s doing—in those moments, Avatar: Fire and Ash reminds us why we go to the movies in the first place.
