I'm onto Season 11 in my rewatch and some my favourite moments are in the run up to Carter and Abby getting together and the initial episodes after they did. If it wasn't for Abby's crazy family they'd still be together.
I know what you mean and I agree.
I'm not keen on a spin off. I think they should leave well alone!
Really sad to see this show end after 15 years but a good finish all the same, at least we know that life at County lives on. Bit bummed that Carter didn't really get his happy ending though ... and I still think him and Abby belong together!
