Kind of a slow burn type of show. Josh Brolin as Royal is very good. He's got that stoic cowboy persona down pat. The supporting cast is also very good. Over all, well-acted and beautifully shot.
The pacing may not be to everyone's liking. Unfortunately, the whole dysfunctional, non communicating family trope is so played out. No one talks to any one in any reasonable way in this family, which does not happen often in real life, and that could take some viewers out.
Summing it up, the story has promise, I hope they tighten up the pace a bit more if it gets renewed for a Season 2. Oh and the premise is quite out there, lol.
