The first season really runs the gamut as far as our emotions are concerned. From hysterical moments of levity to bittersweet romance, they really seem to want to pack it all in. They succeed in this episode where others do not in almost bringing a tear to the eye.
The main plot thread concerns Maurice lamenting the death of his brother. Without his brother, there will be no heir to the Minnifield name, so Maurice decides to adopt Chris as his son. Chris takes to it at first, graciously accepting a free car and meals and tolerating Maurice's sentimental musings on the importance of family. Eventually, though, Chris can't take it anymore. But think about it, would you want to be Minnifield's heir?
Maurice is probably more lonely than the show lets on in episodes prior, and Barry Corbin has the acting chops to pull this off. Chris's acceptance of Maurice's Cadillac means so much to him that it brings tears to his eyes. And usually rock-hard Maurice actually displaying that much emotion almost brings tears to mine.
