Netflix's "American Primeval". Spoilers Possible.
 

Very violent but well acted and written limited series amount clashes between cultures and religions in the American West in the 1850s. Mainly in a what would become Utah and Wyoming.

Just finished watching it. I agree that it is violent but I believe it does portray how life was at that time in those locations. As in any show, it takes some liberties with perspective and reality but it is entertaining.

That it does.

I was thinking about it, thank you!
