After playing catchup I'm finally up to speed and I'm totally on board.
So far the writers have done an excellent job of capturing some of the Elmore Leonard style in building up interesting, quirky characters with only a few lines of dialog.
And then killing them.

I loved dropping into the mob guys in the car in the middle of their Pulp Fiction discussion.
And then killing them in standoff.

The fact the show has no hesitation in killing anyone, quickly and without fanfare gives the show a bit of an unpredictable edge.
CA location really sucks though. At episode three I thought they were in Miami or some place near the beach (like every other show) and completely forgot it was supposed to be Kentucky. Even the architecture feels wrong in a lot of scenes.
And I thought Raylan's rule was that if he pulls his gun he uses it because that's what a gun is for? Twice now he's pulled without firing.
