While the film received praise for its score by Ryuichi Sakamoto and its visual fidelity, some critics noted that the focus on Smith’s personal eccentricities occasionally overshadowed the victims' stories. According to reviewers on Rotten Tomatoes , the film is sometimes "weighed down by self-important direction," yet it remains a "central message" about environmental accountability and the "human beings in this story." Conclusion

The film Minamata serves as a poignant intersection of investigative journalism, environmental tragedy, and the redemption of a fractured artist. Set in the 1970s, it follows W. Eugene Smith (played by Johnny Depp) as he travels to the coastal city of Minamata, Japan, on behalf of Life magazine. His mission was to capture the "Minamata disease," caused by decades of industrial mercury discharge from the Chisso Corporation.

At its core, the film explores how photography can act as a catalyst for social justice. Smith, portrayed as a cynical and reclusive figure, finds a renewed sense of purpose through the suffering and resilience of the Japanese villagers. The movie culminates in the recreation of Smith’s real-life masterpiece, "Tomoko and Mother in Her Bath," illustrating how a single image can humanize abstract statistics and force a global audience to confront corporate negligence.
