Paul Elliott’s review published on Letterboxd:
Reality is repeatedly stranger than fiction. Based on the memoir by Ron Stallworth, Spike Lee chronicles the real-life circumstances in the nineteen seventies which saw Stallworth, an African American detective in Colorado, opportunely slipping into a regional branch of the Ku Klux Klan to expose its members. It's a nearly unbelievable story which is wonderfully co-adapted by Lee and features a dominant performance by John David Washington as the entertainingly adventuresome Stallworth and Adam Driver as his Jewish colleague, Flip Zimmerman.
The film works for a variety of reasons, not least of all because of the excellent chemistry the two leads acquire together, and Lee wisely incorporates scenes of considerable companionship between the two. There's also a multiple of loathsome moments in the company of the vile and hate-spewing racists who detest everyone who doesn't originate from the Aryan race. Lee draws attention to the notion that there is no justice within the United States, and his themes hold palatable comedic touches along with a superb soundtrack with timeless classics by the Temptations, James Brown and Prince. The final moments of the film are emotionally powerful and highlight that the hate still hasn't been driven out, and sadly these malfeasants still hold a presence to this day, standing endorsed by other appointed individuals in power.
