An annotated version would be interesting. TL;DR is that it's a mix of truths, omissions, and lies. He's not wrong that some of the modern borders of Ukraine are a Soviet creation, for example, but completely ignores the fact that it was already in the process of establishing itself as an independent country before the Bolsheviks (as the Ukrainian People's Republic).
Speaking more broadly, one needs to get into fairly ancient history to make sense of various territorial disputes between Russia, Ukraine, Belarus, Lithuania, and Poland, and how it all contributed to ethnogenesis of Ukrainians. In particular, look into Grand Duchy of Lithuania.

It's agitprop, of course. But it's agitprop for both external and internal consumption, and the latter parts are very telling.
