Chicago Fire: Every season ranked from worst to best
10. Season 11
Yeah, we know it’s low. Season 11 had some all-time moments scattered throughout, especially the proposal that Casey (Jesse Spencer) makes to Brett (Kara Killmer), and the mid-season finale where Kidd (Miranda Rae Mayo) nearly died in an explosion. The problem lies mainly with the back end of the season, which was handicapped by the departure of Severide (Taylor Kinney).
The fact that the character left so suddenly, coupled with the fact that started to lie to his wife about his whereabouts, feel forced, and the show had a difficult time of getting its rhythm back without him. We’re hoping that season 12 is able to strike a better balance.
