OMG, it's the Romanovs and they made it boring. It's honestly as dull and boring as an art history documentary. When it really should be chaotic and dynamic and and riveting.
Years back, in the early '00s, the History Channel did a "Russia Land of the Tsars" documentary that isn't exactly as focused, but is still a LOT more... entertaining.
There is no reason why you should sit through a documentary about the Tsars and have it put you to sleep.
The execution was horrible.
