Josh Larsen’s review published on Letterboxd :
BlacKkKlansman is at once a sober, based-on-fact historical drama and a riotously funny prank. In recreating the 1979 police investigation of a Colorado Springs chapter of the Ku Klux Klan—an investigation led by a black detective who posed on the phone as a Klan recruit—Spike Lee gives a shocking amount of screen time to the espousing of white supremacist rhetoric. Yet when that ideology is filtered through an African-American actor’s mouth and Lee’s particular cinematic style, it results in something absurdly, comically pathetic. By pantomiming the KKK’s logic—painting it in whiteface, if you will—BlacKkKlansman exposes such thinking for what it really is: patently false and blatantly idiotic.
