Unabomber has a fascinating subject and a potentially compelling question at its center: What happens when isolation turns into ideological certainty? Janus Metz’s film attempts to answer that question by splitting its story between two timelines, following 16-year-old Ted Kaczynski at Harvard in the late 1950s and the FBI’s pursuit of him decades later. The structure is designed to humanize Kaczynski by showing the alienated, brilliant young man who existed long before he became one of the most infamous domestic terrorists in American history. Unfortunately, the approach ultimately works against the film because it spends too much time explaining Kaczynski’s alienation and not enough time confronting the choices he made with it.
Isolation and alienation are clearly the film’s central themes. Kaczynski enters Harvard as a mathematical prodigy who is intellectually ahead of virtually everyone around him but emotionally and socially unequipped to connect with them. At 16, he is separated from his family, too young to comfortably fit in with his peers and too socially awkward to establish meaningful relationships. His intelligence becomes both his greatest asset and his greatest weakness. The first time he gains confidence in his own abilities, that confidence begins tipping into arrogance. What starts as feeling different from everyone else gradually becomes believing he is better than everyone else.
That is where the film’s exploration of ideological certainty should have become more compelling. Kaczynski’s isolation does not inherently make him dangerous. Plenty of intelligent people experience alienation without becoming violent. The more interesting question is how he turns that alienation into an ideology that validates his own superiority. Rather than accepting that society has failed to accommodate him, Kaczynski increasingly convinces himself that society itself is the problem and that his intellectual conclusions place him above the people around him. The film understands this progression but too often treats the circumstances surrounding Kaczynski as an explanation for his actions rather than emphasizing the responsibility he bears for them.
That becomes particularly uncomfortable because Unabomber seems determined to humanize Kaczynski without sufficiently distinguishing between understanding someone and excusing them. Humanizing a notorious criminal can be valuable when it exposes the complicated path that led to violence. Here, however, the balance feels off. Kaczynski is portrayed as a victim of isolation and institutional experimentation, while the film spends comparatively little time with the people whose lives were destroyed by his campaign. The result risks shifting attention away from the man who made the choices and toward the circumstances that surrounded him.
Jacob Tremblay nevertheless gives the film its strongest performance. Playing Kaczynski at 16, Tremblay captures the uncomfortable combination of intelligence, insecurity and resentment that makes the character compelling. He doesn’t portray him as an obvious monster. Instead, there is a nervousness to Kaczynski that gradually gives way to something more troubling as he realizes just how intelligent he is. Tremblay understands that arrogance is not always loud. Sometimes it manifests as the quiet conviction that everyone else simply isn’t capable of understanding what you already know.
Russell Crowe is even better as Dr. Henry Murray, the Harvard professor who recruits Kaczynski into a series of psychological experiments. Crowe gives Murray a sly, authoritarian presence that is tempered by enough charisma to explain why people would gravitate toward him. He initially presents himself as an intellectual mentor, but Crowe gradually allows the mask to slip. There is something unsettling about the way Murray exercises control while maintaining the demeanor of a sophisticated academic. Crowe understands that the character doesn’t need to be overtly sinister to be intimidating, making him the most magnetic presence in the film.
Shailene Woodley’s FBI agent Joanne Miller provides an intriguing counterpoint to Kaczynski. The character is fictionalized, but her approach to the investigation allows the film to establish a parallel between two exceptionally intelligent people who refuse to abandon their instincts. Miller focuses on language and behavior to identify the Unabomber while facing resistance from colleagues who don’t initially share her confidence. Her male counterparts are hindered by their own institutional assumptions and egos, while Miller is able to adapt her approach and persuade them. The distinction between the two characters is important: Both trust their intellect, but Miller uses hers to connect ideas and bring people together while Kaczynski uses his to build walls around himself.
The film’s biggest structural problem, however, is that it gives away too much too soon. The identity of the Unabomber is hardly a mystery, of course, but that isn’t the problem. The problem is that the film reveals the key breakthrough in the manhunt so early that much of the FBI storyline loses its suspense. Instead of immersing the audience in the years-long search for a man who had successfully evaded the FBI, the movie rushes toward the climax. A story about one of the most famous manhunts in American history should have found tension in the investigation itself. The film instead treats the pursuit as a framing device for Kaczynski’s origin story.
That choice is especially frustrating because the manhunt provides everything a great thriller needs. There is institutional conflict, linguistic analysis, false leads, public pressure and the growing realization that the FBI is searching for someone far more elusive than expected. The real investigation also offers an opportunity to explore the contrast between Kaczynski’s belief that he could outthink society and the painstaking process by which investigators eventually understood him. Unabomber has all of those ingredients at its disposal but seems more interested in answering why Kaczynski became who he was than showing how difficult it was to catch him.
The film also struggles to establish a convincing connection between Kaczynski’s Harvard experience and the man he eventually became. Murray’s experiments are disturbing and Crowe makes them compelling, but the screenplay leans too heavily on the implication that this experience helped create the Unabomber. There is an important distinction between an experience contributing to someone’s psychological development and an experience causing someone to become a domestic terrorist. Unabomber occasionally blurs that line, making the connection feel more deterministic than the story can actually support.
For all of its flaws, the film is not without merit. Tremblay and Crowe elevate material that often feels too conventional for its subject, while Woodley provides a useful thematic counterweight to Kaczynski. There are moments when the film genuinely captures the danger of intellectual certainty, particularly when Kaczynski begins treating his own conclusions as unquestionable truths. The tragedy isn’t that he was intelligent. It is that his intelligence became the foundation for an increasingly rigid worldview in which disagreement became evidence of everyone else’s inferiority.
Ultimately, Unabomber is a frustrating missed opportunity. This is a story about a brilliant and deeply alienated man who transformed his resentment into an ideology and ultimately used that ideology to justify violence against innocent people. That is inherently compelling material, but the film spends too much time trying to explain Kaczynski and not enough time examining the consequences of his choices. The two-timeline structure never fully comes together, the manhunt is prematurely deflated and the movie’s attempts at psychological explanation occasionally risk becoming moral simplification. Tremblay and Crowe are both better than the material surrounding them. Unabomber could have been a gripping examination of isolation, arrogance and ideological radicalization. Instead, it becomes another example of a fascinating true story that Netflix had the resources to tell but not the screenplay to fully realize.
