I really think this was one of the best episodes yet. The dialogues are beautifully written and wonderfully acted. I also found myself laughing more throughout this episode than any other. The one liners were great. When I saw the low score of this episode I felt compelled to make it known that those who are rating in low just don't understand this show for its originality and substance.
I will say, however, that the deep and witty dialogue in this show tends to remind me of the show that put Timothy Olyphant on the map (which is Deadwood). The writers here definitely want to take the show beyond just shoot-em-up non-stop action, and I appreciate that very much!
