liked the show, not the ending
I recently rewatched all the episodes of Longmire via streaming. Just as I did originally I fully enjoyed the series.
But I take exception to a number of things in the wrap up.
While I could buy Walt's retiring as Sheriff it is inconceivable to me that Cady would be his successor in the job. Vic, Ferg and even Zach seem much more suitable to the job.
And while it was OK that Walt and Vic finally hooked up it didn't seem appropriate that she'd be on the porch happily waving him goodbye as he heads out to find the lost treasure.
When a series is this good and then stumbles across the finish line it does (IMHO) take something away from the total.
