When I watched seasons 5 and 6 back in the day, I thought that Kellerman was justified in the Luther situation and that Stivers, Lewis, and Falsone were wrong in their condemnation of Kellerman for different reasons. No almost 30 years later on rewatch, I am still on Kelleman's side, although some of his actions after the shooting are impossible to defend.
I remember thinking that season 7 was not as good as the first 6 when it originally aired and on rewatch, it is not as bad as I remember. You can really see the NBC influence on the show in later seasons. 7 is almost like Homicide 90210 with all of the talk of who likes who drama
