The controversy of Dr. Stone’s ending: A satisfying conclusion or a missed opportunity?

When Dr. Stone began in 2017, it offered a rare premise in the world of shōnen manga. Instead of power-ups, curses, or devil fruits, the series revolved around a simple yet audacious idea: rebuilding civilization from scratch using science.

When the manga concluded in March 2022, reactions were mixed. Some praised the ending for remaining hopeful, ambitious, and open-ended, while others felt it was rushed, incomplete, and frustrating, particularly in resolving the series’ major mysteries. The controversy boils down to this question: Did Dr. Stone stick the landing, or did it squander its vast potential?

Perhaps the most divisive point is the reveal of Why-Man, the entity behind the global petrification event. Throughout the series, Why-Man’s eerie transmissions raised expectations. Was he a future version of Senku? A sinister human mastermind? A cosmic intelligence?

Instead, the reveal was that Why-Man was a swarm of alien-like artificial lifeforms—the Medusa devices themselves—self-replicating machines seeking survival through petrification. Their logic? Find an intelligent species, petrify it to preserve it, and wait for that species to rebuild enough technology to produce more Medusas.

On paper, this explanation has a certain pulp sci-fi flavor. It ties the petrification devices directly to the antagonist and frames Why-Man not as malicious but as an alien AI with flawed logic. Yet for many readers, it was unsatisfying.

The Medusas’ cryptic response, “Do you humans know where you come from?” felt like a dodge rather than an answer. Fans had hoped for clear origins, motives, or cosmic stakes, but instead received ambiguity.

The character question in Dr. Stone

Another element fueling the controversy is character development in Dr. Stone, or the lack thereof, in the later arcs. Early arcs fleshed out Tsukasa, Gen, Chrome, and others with meaningful growth. But as the story shifted toward global exploration, side characters became increasingly sidelined.

Taiju and Yuzuriha’s romance is a prime example. The manga begins with Taiju’s long-delayed confession, framing it as central to his arc. Yet their relationship receives minimal attention afterward, culminating in a sudden marriage reveal in the final chapter. Similarly, Tsukasa’s bond with his sister fades into the background after her revival.

Readers invested in the side characters found the abrupt wrap-up hollow. Though Senku’s scientific journey took center stage, the emotional arcs of supporting characters were largely overlooked.

Untapped potential: What could have been

One of the most heated fan debates revolves around the untapped narrative potential left behind in Dr. Stone. The Medusa devices are essentially the ultimate McGuffin: they can petrify, heal, and even bestow immortality. After Hyoga’s revival during the second worldwide petrification, Senku, Gen, and Tsukasa agree to keep this secret hidden.

The scene hinted at vast potential conflict. If the secret spread, wars, power struggles, and a fight for immortality seemed inevitable. Yet the manga ignored these possibilities, ending before such tensions could develop.

Some fans also wished to see Senku reverse-engineer the Medusa technology and apply it to human advancement. Imagine a final chapter showcasing futuristic cities, flying vehicles, or medical breakthroughs. Instead, the story closes with Senku beginning research into time travel—a poetic but frustratingly vague gesture.

Senku’s choice to revive everyone, including criminals and dictators, was another untapped narrative thread. It could have sparked a moral crisis when his actions led to conflict. In desperation, might he have considered re-petrifying humanity?

Such a scenario would have echoed the series’ cyclical themes while raising new ethical stakes. By ending before these possibilities could unfold, Dr. Stone left many fans feeling as if the authors pulled the brakes too early.

Final thoughts

Personally, I think Dr. Stone succeeded in capturing the spirit of discovery, even if it stumbled in execution. The unanswered questions and rushed pacing are real flaws, but they don’t erase the joy of watching Senku create glass, antibiotics, or a rocket from scratch. While the ending may not have been ‘10 billion percent satisfying,’ it reinforces the core message: knowledge and curiosity remain humanity’s most powerful tools.
