 Countdown, a 13-episode thriller from Chicago Fire creator Derek Haas, premiered June 25, 2025, on Prime Video, with Jensen Ackles leading as LAPD detective Mark Meachum. After a DHS officer’s murder, Meachum joins a covert task force to unravel a nuclear conspiracy threatening LA. The series kicks off with a bang, delivering fast-paced action and Die Hard-style thrills, but critics note its clichéd plot and uneven pacing, with a 36% Rotten Tomatoes score. Fans praise Ackles’ charm and the ensemble’s chemistry, likening it to Lethal Weapon, though some find the dialogue macho and repetitive. With weekly episodes through September 3, 2025, it’s a binge-worthy summer ride for action fans, despite a weak finale. Stream it now on Prime Video
