The Bosch saga, which captivated 15 million fans across seven seasons on Prime Video from 2014 to 2021, is roaring back with a prequel series greenlit by MGM+ on October 15, 2025, titled Bosch: Start of Watch, a gritty origin story set in 1990s Los Angeles following rookie cop Harry Bosch’s early days in the LAPD, starring Cameron Monaghan as the young detective and Omari Hardwick as his veteran mentor Eli Bridges, a fresh character promising moral mazes and high-stakes hits that honor Michael Connelly’s novels while carving a new chapter in the franchise’s legacy. Created by Connelly and executive produced by Henrik Bastin, the 10-episode arc—filmed in Los Angeles from January to July 2025—plunges viewers into Harry’s “rookie resolve” amid riots and rookies, his “inquiry” a inquiry into the shadows that shape a star.

The saga’s searing surge? Spellbinding: The pilot catapults Harry into the fray, a Rodney King riot hit etched with doubt, unspooling a conspiracy where rookies conceal crimes and veterans harbor grudges. Monaghan’s Harry? A “masterclass in mettle,” his fresh-faced fire warping to weary watchfulness, unraveling a ripple of regrets where a mentor’s “hit” surfaces as sabotage. Hardwick’s Eli? A “veteran of venom,” his grizzled grit cracking under the creep of compromise. Co-stars deepen the drama: Mimi Rogers as a “haunted handler” with a sting, Jamie McShane as a “calculating” confidant with secrets. Connelly’s script quivers with quips—”The badge weighs heavier than the gun”—but the “brutal” brutality bites: a botched riot raid buries hope, a VVIP viper’s venom turns ally to assassin.

The “new chapter thunderclap”? Seismic: As a prequel to the Titus Welliver-led Bosch (now in Bosch: Legacy on Prime, S4 2026), Start of Watch amps the “pacy” probe with “spooky” soundscapes and “authentic” 90s accents, LA’s “eerie fog” amplifying “grim themes.” The Guardian‘s Lucy Mangan raves “pacy, poignant drama” with Monaghan’s “reliably raw” heart; The Independent‘s Ed Power hails Hardwick’s “Icily Glamorous” intensity and the “haunting” score. Variety‘s Owen Gleiberman praises the “confidence, style, authenticity.” Skeptics? “Mired in machismo,” but the 1-in-2 clue-to-cliff ratio hooks, BARB metrics outgunning The Jetty.

This isn’t crime caper; it’s a clarion for cunning, the prequel’s “rookie” a requiem for the resolute where badges bend and truths triumph. Harry’s hit? Harrowing. Eli’s edge? Electric. 2026? Not a drop—a deluge. Binge it; the riots ripple, the resolutions rend. Monaghan’s mettle? Mesmerizing. The obsession? Overnight, inescapable.
