Netflix's Unabomber Wants a Tidy Answer for Why Kaczynski Became a Terrorist. History Doesn't Give One, and Neither Should This Movie

I want to be upfront about why I sat down for this one, because a Netflix biopic about a domestic terrorist isn't exactly a relaxing Thursday night. Here's why: Unabomber is the third time in nine years a studio has tried to put Ted Kaczynski on a screen, and each attempt has made a completely different bet about what actually explains him — a Discovery Channel procedural that bet on the FBI's side of the story, an art-house feature that bet on total isolation and his own diaries, and now a Netflix biopic betting on a single Harvard classroom. I watched all three back to back this week. Only one of them is trying to sell you a cause, and it's the newest, the most expensive, and, based on where the reviews are landing, the least convincing.

What critics are actually saying

The reception has been rougher than Netflix's marketing wants you to notice. Variety called it a hokey retread with a TV-movie gloss, and said Tremblay doesn't quite convince as the teenage Kaczynski. The Hollywood Reporter's bottom line was blunter still — "a faint sketch of a killer as a young man" — and argued that Tremblay, effective at conveying youth and alarm, plays the role as bratty rather than genuinely menacing. RogerEbert.com's review was similarly unimpressed with the writing, though it credited Crowe with turning in one of the film's only fully engaging performances. TheWrap went further, calling the finished film unfocused and padded, and The A.V. Club argued that even a subject this singular can't escape what it called the generic streaming-biopic curse. IndieWire was the most generous of the bunch, calling the film often insightful but also dangerously simplistic in how it resolves Kaczynski's psychology.

What almost nobody disputes is Tremblay himself. Multiple reviews, including ones that otherwise pan the movie, single out his physical commitment to the role — the voice cracks, the wide-eyed alarm, the discomfort in his own skin. It's his second film in two years built around a young man radicalizing into extremism, after 2025's Sovereign, and it's becoming a genuine specialty for an actor best known for playing a traumatized child in Room over a decade ago. The consistent complaint isn't that he's miscast. It's that a script this scattered never gives his performance anywhere to build toward.

The Harvard experiment, fact-checked

Here's the part of the movie I actually think is worth taking seriously, separate from whether it's well made: the Harvard study at its center really happened, and it really was unethical. Between 1959 and 1962, psychologist Henry Murray recruited 22 Harvard undergraduates, Kaczynski among them at age 17, into a study that involved writing personal essays about their beliefs and then being subjected to what Murray himself described as "vehement, sweeping and personally abusive" attacks on those beliefs, delivered by an anonymous interrogator while electrodes monitored their physiological stress. The sessions were filmed, and subjects were later made to watch their own reactions play back, repeatedly. Kaczynski spent roughly 200 hours in the study over three years. None of that is invented for the movie. It's in the historical record, and it's genuinely disturbing on its own terms.

What's shakier is the throughline the film draws from that study directly to the bombs. Some writers, including biographer Alston Chase, have connected Murray's wartime work with the OSS — a forerunner to the CIA — to speculation that his Harvard study was quietly backed by the CIA's MKUltra mind-control program, and a 2017 Discovery Channel dramatization presented that link as settled fact. It isn't. Most careful accounts, including Wikipedia's own sourcing, note there's no direct evidence tying Murray's specific study to MKUltra funding, even though the two ran in the same Cold War era and shared some of the same unsettling premise. Kaczynski himself weighed in on this exact question years ago, calling the "MK-Ultra torture" framing in that earlier series "pure fiction" and insisting the study amounted to one unpleasant half-hour session, not sustained torment. He also said, in his own words, that he was "quite confident" the experiment had no significant effect on the course of his life. Unabomber doesn't invent the CIA theory — it inherited it from a decade of true-crime retellings — but it leans on that theory as hard as any version yet, and that's precisely the reductive move IndieWire and The A.V. Club flagged in their reviews. Dramatizing a real unethical experiment is legitimate history. Using it as the one clean explanation for a 17-year bombing campaign is a different, much sloppier thing, and it's the difference between a movie that illuminates its subject and one that just wants a satisfying ending.

Two timelines, one invented FBI agent

The film's second timeline follows the 1990s manhunt through Shailene Woodley's Agent Joanne Miller, a character invented whole-cloth for this movie — there was no real FBI profiler by that name central to Kaczynski's capture. That's a defensible dramatic choice on its own; composite and invented characters are standard biopic shorthand. What bothers me more is what it displaces. The person who actually broke the Unabomber case wasn't a fictional agent — it was Kaczynski's own brother, David, who recognized Ted's writing style and ideas in the published manifesto and, after an agonizing decision, tipped off the FBI. That's arguably the single most human, most consequential detail in the entire real story, and by building an invented FBI protagonist to carry the manhunt half of its plot, the film treats David's role as one supporting beat among several rather than the load-bearing one it actually was. You can build a compelling procedural without a composite agent. Manhunt: Unabomber did it eight years ago, centering the real profiler who pioneered forensic linguistics on the case, and it's still the best-reviewed of the three dramatizations, for reasons that go beyond nostalgia.

How it stacks up against Manhunt and Ted K

Since this is now the third time Hollywood has tried to explain the same man, I watched all three back to back and built the comparison nobody else seems to have bothered making — format, star, critical reception, and my own one-line verdict on each.

None of that means Unabomber is worthless. It's the first of the three to dramatize the Murray study with any real production value, and for a lot of viewers who've never heard of Henry Murray or read Alston Chase's book, that alone has value even if the movie oversells the conclusion it draws from it. But it's a smaller, narrower contribution than the marketing wants it to be, and going in expecting a documentary-grade account of why Kaczynski did what he did is going to leave you as unsatisfied as it left me.

The fight over whether this should exist at all

There's a separate argument happening around this movie that has nothing to do with whether it's any good, and it's worth taking just as seriously. Since the trailer dropped, outlets covering the backlash have reported that relatives connected to Kaczynski's victims have criticized Netflix over the project, arguing that centering a young, sympathetic, wounded version of him — rather than the man who mailed sixteen bombs over nearly two decades — risks softening how audiences remember what he actually did. It's the same fight that's followed nearly every prestige true-crime dramatization of a real perpetrator this decade, from Dahmer to Bundy, and it doesn't resolve cleanly just because a studio adds a disclaimer or a two-timeline structure meant to signal moral seriousness.

My honest read, for what it's worth: I don't think a film forfeits the right to exist just because it centers a perpetrator's interiority — some of the most valuable true-crime work ever made does exactly that, carefully. But "carefully" is the operative word, and carefully is not the adjective seven major critics reached for this week. What I keep coming back to, and the one genuinely hopeful thing I'll say about this whole cycle, is that the backlash itself is louder and more immediate than it would have been even five years ago. Audiences are getting sharper about demanding that films earn the right to dramatize real harm, not just assume it. Unabomber didn't clear that bar for most of the people who reviewed it. But the fact that the bar exists now, publicly and loudly, and that a streaming giant has to answer to it before a movie even finishes its opening weekend — that part of this story is actually moving in the right direction, even when the movie itself isn't.
