Empire Of The Tsars: Romanov Russia - 2015 - 7/10

Lucy Wolsey hosts three part documentary covering 300 years of the Romanov Dynasty.
Episodes focus on Peter The Great, Catherine The Great, and Nicholas The Not-So-Great.

Wolsey is always enthusiastic and prepared, and seldom offers personal opinions or snarky comments.
As history, much of this will be old hat to buffs.
The chief draw is that she seems to have been allowed unrestricted access to many areas inside palaces or behind the scenes.
