More than two decades after the murders of these two rap superstars, the search for their killers has left us with little more than countless theories, shitty holograms, and, now, the first season of USA's promising Unsolved franchise. Don't expect any The Jinx-like twists here, but their tragic, intertwined stories are compellingly told using multiple timelines, which track, roughly, the years leading up to Tupac Shakur's assassination in 1996 and Christopher "the Notorious B.I.G." Wallace's in 1997, the ensuing LAPD investigation into the latter (with Westworld's Jimmi Simpson portraying a stymied detective), and a mid-2000s task-force investigation (with team members played by Josh Duhamel, Bokeem Woodbine, and Wendell Pierce). While Unsolved doesn't reach the heights of recent season-long true-crime standouts FX's The People v. O.J. Simpson: American Crime Story or Netflix's Wormwood, the 10-episode tale's superb casting and occasionally zippy dialogue elevate it above straight procedurals like last year's Manhunt: Unabomber.
