WHAT IT'S ABOUT

Ken Burns' now-classic "The Civil War" was seen by 40 million viewers over 11 hours in September 1990, blunting commercial network premieres, while becoming one of the most-watched PBS series in history. Now, after undergoing what's called a "4K" restoration -- in which the original film has been rendered in hi-def, or 3,840 lines of resolution, versus the original 480 lines -- "TCW" is back for a 25th anniversary telecast.
