I don't know the ratings but I found the show got worse as the seasons went on. From what I've seen with on line commentary, I am far from alone in that. Characters became less likable, [except Shannon who was always peak unlikable] from what others said. I kept watching it out of habit but I am glad they pulled the plug.Here's where the problem lies, Kim's Convenience was nowhere near plateauing, it's popularity was increasing. The writers threw away a cash cow.
Could they have done new story lines, sure, did I care, no.
I gave Strays a chance but much like whats her face, it was pure cancer. As for Burbs the commercials didn't really do it for me. Buddy presents alright on screen but he works better as the best friend than as the primary. Unless it's perhaps a different role.
