Welcome to the 21st Century Seth Bullock! Wife and I liked what we saw in this episode. I hope they can continue the quality.
I am glad to see that they have been careful to cast believable actors in the roles. My biggest gripe with Hollywood is they really don't know how to cast for southern characters. Nick Searcy is perfect in the US Marshall's bureau chief. He speaks with a southern accent normally (he is from North Carolina) and has that "small town southern" aire about him. When he was in From the Earth to the Moon, he played Wisconsin born and raised Deke Slayton and while Searcy did a good job in the role, being the space buff I am, knowing Slayton DIDN'T speak with a southern accent, made the character less believable to me. My number one southern casting faux paux? The great actor Joe Pesci (who I like) as the southern David Ferrie in JFK. Pesci can play MANY roles other than a Mafia hood from Jersey, but a southerner, he can't. It would be like asking Emily Proctor to play a Jersey Girl. She would do a good job, but she would never be able to pull it off. That is a totally foreign world to her, like it was for Pesci. I hope they continue to keep that in mind when casting for this. I would hate they screw this show up with little stuff like that.
I also don't know how the California locales will work either. The Andy Griffin Show was shot in California and I can tell you, those lake locales don't look ANYTHING like the mountains of North Carolina or even the foothills of Mount Airy, NC, where that show is based on.

"Mount Pilot" of Andy Griffin fame. In reality, this is Pilot Mountain (and town of same name at the base), about 10 miles south of Mount Airy, NC and is one of three extent volcano domes in the area. Never saw anything like that on the show.
Will be interesting to see how the mountains of California will translate into the coal fields of WV.
But for the time being, we in.
