Hollywood has a history of journeying down Vietnam’s rivers and through its jungles to heal the heartbreak shrouded in the ruins of war. Spike Lee’s Da 5 Bloods (B) starts innocently enough with a quartet of affable modern-day African-American veterans reuniting in a Ho Chi Minh City hotel to embark on a search for the buried bones and bullion left behind by a fallen platoon leader, played in flashbacks by Chadwick Boseman. This memory film’s twisty heist plot is also a bit of a Western, as in a commentary on Western Civilization, always urgent even if occasionally overreaching or delving into myriad detours of flourish. Delroy Lindo gives a forceful, hot-headed performance as the primary old timer, the MAGA hat wearing Paul, who like his comrades, also plays himself at an earlier age without the magic of de-aging special effects. Lindo gives an astonishing muttering monologue after a critical series of action sequences that’s career best. He’s like a land mine one step away from self-actualization, and he’s fascinating to watch in his masterclass of acting. Lee’s crisscrossing techniques through history gracefully bridge past transgressions to a tableaux of modern topics ranging from imperialism to contemporary class and racial politics. The movie comes most alive in its celebrations of brotherhood and fatherhood; Jonathan Majors is memorable and moving as Paul’s estranged college son. Terence Blanchard’s music is stirring accompaniment to action and ache, with occasional soothing echoes of Marvin Gaye. After his brilliant BlacKKKlansman, Lee’s follow-up is a bit more narratively sprawling but thematically daring. The thoughtful director’s change of venue from American soil enables no less a promised land of issues to travel and unravel.
