One Chicago Crossover Review: An Overpromised & Underdelivered Franchise Crossover Fails To Balance Its Storytelling

The 2025 One Chicago crossover is a celebration of NBC's premier dramas, but it is bogged down by imbalanced storytelling made worse by failing to establish the stakes at hand. After six years, Chicago Fire, Chicago PD, and Chicago Med have gathered once again for Wolf Entertainment's Windy City tradition. The last time Firehouse 51, Gaffney Medical, and Intelligence worked a whole shift together was back in 2019, with an ominous case that threatened Chicago with a virus attack. It would be an understatement to say that much has changed since then, with many major characters having left One Chicago since.
