Critical response On
Rotten Tomatoes, the film has an approval rating of 96% based on 450 reviews, with an average rating of 8.3/10. The website's critical consensus reads, "
BlacKkKlansman uses history to offer bitingly trenchant commentary on current events—and brings out some of Spike Lee's hardest-hitting work in decades along the way." On
Metacritic, the film has a weighted average score of 83 out of 100, based on 56 critics, indicating "universal acclaim". Audiences polled by
CinemaScore gave the film an average grade of "A−" on an A+ to F scale, while
PostTrak reported filmgoers gave it an 85% positive score and a 67% "definite recommend". For
IndieWire, David Ehrlich gave the film a grade of "B+" and wrote that it is "far more frightening than it is funny", and "packages such weighty and ultra-relevant subjects into the form of a wildly uneven but consistently entertaining night at the movies".
A. O. Scott, writing for
The New York Times, saw the film as both political and provocative in opening up discussion on timely subject matter following Charlottesville. He stated, "Committed anti-racists can sit quietly or laugh politely when hateful things are said. Epithets uttered in irony can be repeated in earnest. The most shocking thing about Flip's (Adam Driver's undercover detective role) imposture is how easy it seems, how natural he looks and sounds. This unnerving authenticity is partly testament to Mr. Driver's ability to tuck one performance inside another, but it also testifies to a stark and discomforting truth. Maybe not everyone who is white is a racist, but racism is what makes us white. Don't sleep on this movie." In his review of the film for
Vulture,
David Edelstein found the film to be a potent antidote for previous films that Lee sees as unduly supportive of the racist viewpoint in the past, such as Griffith's
The Birth of a Nation. Edelstein stated: "Lee himself has a propagandist streak, and he knows nothing ever sold the message of white emasculation and the existential necessity of keeping blacks down as well as Griffith's 1915 film. It revived the Klan and—insult to injury—is still reckoned a landmark of narrative
filmmaking. If there were no other reason to make
BlackkKlansman, this one would be good enough." Filmmaker
Martin Scorsese praised the film, saying "The picture takes you to a safe place — we're watching a movie, it's up on a screen — and suddenly we're catapulted into now ... Right next to you. Because it's not only real, what you're seeing up there on the screen — it's happening. It is happening. And it's sanctioned by government...It transcends the medium, what he did there in the last 10 minutes. It's cinema and it's beautiful." Filmmaker
Boots Riley, whose feature film debut
Sorry to Bother You also premiered in 2018, criticized the film for its political perspective. While Riley called the craft of the film "masterful" and cited Lee as a major influence on his own work, he felt that the film was dishonestly marketed as a true story and criticized its attempts to "make a cop the protagonist in the fight against racist oppression", when Black Americans face structural racism "from the police on a day-to-day basis". In particular, Riley alleged that the film glossed over Stallworth's time spent working for
COINTELPRO to "sabotage a Black radical organization" and objected to the film's choices to portray Stallworth's partner as Jewish and to fictionalize a bombing "to make the police seem like heroes". Lee responded in an interview with
The Times on August 24, stating that while his films "have been very critical of the police ... I'm never going to say that all police are corrupt, that all police hate people of color."
