Mononoke the Movie: Chapter III Review: A Visually Stunning Finale With Baggage It Can't Shake

Three films, one director, and a story that has spent two years refusing to let the Ooku's inner chambers feel safe again. Mononoke the Movie: Chapter III - The Curse of the Serpent premiered worldwide on Netflix September 29, closing out the trilogy Kenji Nakamura built from the 2007 cult series, and it closes it as the best-looking entry by a real margin, even while carrying a piece of real-world baggage the story itself cannot quite absorb.

The mystery this time

The Curse of the Serpent opens with peace nominally restored to the Ooku, which by now functions as this trilogy's most reliable warning sign. The Medicine Seller senses something still lingering. That something turns out to be tied to a conspiracy stretching back roughly 150 years, rooted in the Ooku's own founding, and the immediate threat is a Snake God Mononoke strangling maids inside the inner chambers.

Where Phantom in the Rain and The Ashes of Rage each worked as largely self-contained mysteries, closer to case-of-the-week horror than serialized plot, Chapter III is different on purpose. This is the first film in the trilogy that genuinely requires having watched the other two to follow what is actually at stake. That is a real structural shift, and it works. Rather than spending runtime re-establishing the Medicine Seller's methods or the Ooku's politics from scratch, the film builds directly on relationships and history the audience already has, and uses that saved time to deepen a mystery that reaches back further than either previous film attempted.

Where the film is strongest

The animation is where Chapter III separates itself. The trilogy's signature look, flat, ornamental compositions closer to a moving woodblock print than standard television or film animation, gets pushed further here than in either previous entry. Studio Kafka and EOTA's work in this finale is sharper and more confident, and the film's art direction backs it up with some of the most striking imagery the franchise has produced. The score matches that ambition, blending traditional Japanese vocal and instrumental work with modern elements in a way that reinforces the film's sense of ceremony without tipping into pastiche.

The Medicine Seller's mystery-solving structure, uncovering a mononoke's Shape, Truth, and Reason before the Sword of Exorcism can be drawn, gets its most difficult puzzle yet here, and the film earns the extra effort it asks of the audience to track it.

What holds it back

The film's central complication is not on screen. Takahiro Sakurai returns to the cast in Chapter III, the same actor whose extramarital affair scandal led to his original replacement earlier in the franchise's run. That casting decision lands badly against a trilogy that has consistently centered women's suffering inside a rigid, male-controlled palace system. It does not break the film mechanically. The mystery still resolves, the animation still holds up, the Snake God plot still lands. But it sits there as a real-world contradiction the story cannot script its way around, and for viewers already invested in what this trilogy has been saying about the Ooku's women, that context is difficult to set aside for two hours.

How it closes the trilogy

Nakamura's choice to end the story here, after one television series and three theatrical films across nearly two decades, reads as deliberate rather than open-ended. Chapter III does not leave obvious room for a fourth chapter, and going by how tightly it wraps its central conspiracy, that appears to be the point. As a piece of animation and mystery construction, it is the strongest entry in the trilogy. As a thematic closer, it is undercut by a decision made off screen that the film never fully reckons with on screen.

With all three films now streaming on Netflix at once for the first time, Chapter III is easiest to judge as the ending of a single long story rather than a standalone watch. Taken that way, it delivers on the mystery and the visuals, and it is worth knowing going in that the real-world context around its cast is going to affect different viewers very differently.
