Chicago Fire’s 300th Episode Fasttracks Its Death By A Thousand Cuts | Review

For a milestone as rare as hitting 300 episodes, Chicago Fire fails to deliver a memorable celebratory episode. As NBC's fall 2026 slate continues to rely on fully-established projects led by the Law & Order franchise, One Chicago's inaugural series continues to build its own legacy as the third-longest-running procedural on the network. Premiering in 2012, Chicago Fire is arguably the most popular first-responder show on TV right now. Aside from paving the way for spinoffs, such as Chicago PD and Chicago Med, it also inspired a string of shows in the same sandbox, with both ABC and CBS trying to replicate its success.
