Not sure how close to the truth this is. But fascinating and timely.
My advice - PAY CLOSE ATTENTION because it is hard to work out which side various soldiers are on at times.
Watch right till the end. NO SPOILERS. Right to the very end and the credits too.
A tad confusing and overlong, but watchable. And the cracker reveal at the end is great (NO SPOILERS) but I am unsure if that is based on truth or is fiction.
Those not familiar with Ukraine history might like to watch MR JONES or THE OCCUPATION to learn more before watching this. Like most mainland European countries, borders and populations have changed over the centuries, the cause of so many wars. We in Britain are luckily an island, and left that tribal stuff behind with Alfred the Great in 900 AD or soon thereafter when England was united.
