I enjoyed the Terminator and Lethal Weapon TV shows as well. Too many good TV shows get canceled for crap. All I watch is Chicago P.D. and I watch the Rookie with the wife. I watch old Chicago P.D. reruns on ION TV and they seem better than the new ones.
A serious subject such as law enforcement, add in comedy and a family feel. How can you lose? It is like CBS in the 60’s era. They hated that Beverly Hillbillies was #1. I am not sure who did Petticoat Junction, Green Acres, and Gilligans Island. I am thinking that ALL were from CBS. They were embarrassed that people watched and enjoyed this sort of humor. Even Hee Haw was popular, so they moved that around until it ended up off of the major networks.
Point is, the major networks have always hated middle America. Those who are happy with America, and want to be entertained and laugh.
