In Spike Lee's Da 5 Bloods, four Black war veterans return to Vietnam. They're there to retrieve the remains of a fellow soldier, who died on the battlefield. They're also after millions of dollars' worth of gold bars they'd hidden during the war. Da 5 Bloods was supposed to roll out in theaters this summer; instead, it dropped on Netflix earlier this month. But it's still a major Oscar contender — a war epic that's grand in scope, with generational scars that run deep.
