Great pilot to an entertaining series. The acting and the writing in this show are really great. It goes without saying that the special affects are amazing.
The one thing that seemed to be an unexplained was right near the beginning. When the Marshal and precocious hellion he is escorting cross country, they pass a car.
The miscreant is surprised to see herself waving at her from the other car, and the same Marshall driving the other car as is driving her car!
The one thing that one learns right off the bat about this town is that tragedy happens quickly, without any warning - and they are used to it.
That, and of course, they are neck deep in miracles.
