“HATFIELDS & MCCOYS” – Over the years, most of us have heard of the famous 19th century clash of backwoods clans. But few of us actually know what got the rumble rolling, or that it very nearly launched a war between Kentucky and West Virginia. This six-hour miniseries, airing over three nights, provides all the details and then some. It’s bolstered by vivid performances from Kevin Costner as Devil Anse Hatfield (yes, that’s his real name), and Bill Paxton as Randall McCoy. Also featured in the standout cast: Tom Berenger, Powers Boothe and Mare Winningham. 9 p.m. Monday, History Channel.
