Netflix's new limited series is set in the Old West, but it's much more than a Western, says star Kim Coates, who plays Brigham Young.

Peter Berg directs an epic six-part drama about the Mountain Meadows Massacre of 1857, in which more than 100 settlers were murdered by militant Mormons.

This is a project that will rise and fall on the strength of its action, adventure, thriller, suspense, and survival sequences.
