I thought that's what they were hinting at when he and Jo were walking away at the end.
Did the Sheriff retire, so that Jack could have his job?
I hope so too. Maybe they'll have him appear once in awhile like a Sheriff Emeritus or something. I've really enjoyed his work ever since The Art of War.
I hope that we get to see him again because Maury Chaykin is awesome.
That's what I kind of like about it. It's not a straight comedy but more of a dramedy which comes with characters who problems; dad/daughter conflict, the deputy who has trouble getting a date, etc.
Other than the daughter, my only complaint is that the tone of the show seems to abruptly switch from whimsical to creepy, which is a little jarring. It's like, ooh, this is fun, what neat gadgets, what cute little awkward nerds, OMG THAT DUDE'S LEGS ARE GONE!!!
The only thing I don't get is Lowjack. Taggert is after him yet the Sheriff invited him and told him to help himself to the fridge.
