Even when the show was at its most sitcom-y (while bucking many sitcom standards, it did fall prey to the New Job or the dreaded Swapping Places storylines) it still managed to consistently rise above the formulaic, often parodying one standard even while stuck firmly in another, and that made it feel quite comfortable. The last season may not have been their strongest, but at least there was no severe decline, and that's what Brent Butt was hoping to avoid when he announced the end of the show after the sixth season. He did good.
And maybe, most of all, it's just reassuring to know that despite the fact that there will be no more new episodes, the characters will still live on in their small town universe doing their thing just as they had. I mean, if you think about it, the biggest permanent change to come to the town happened in the very first episode, when Lacey showed up to re-open her aunt's coffeeshop. From then on the show was set. Ending the series before a cast member left (bringing on a replacement) or a creative team decision to "go in a new direction" means that Dog River will always stay what it is. Was. And I guess it's nice to think about that.
