“BlacKkKlansman”

B+

An African-American detective infiltrates the local chapter of the Ku Klux Klan. It’s uneven, but wildly entertaining and wisely prescient. Starring John David Washington, Adam Driver and Topher Grace. Directed by Spike Lee. (Ann Hornaday, Washington Post) Rated R for crude language throughout, including racial epithets, disturbing/violent material and some sexual references. At metro theaters. 2 hours, 14 minutes.
