Unsurprisingly, all the negative reviews are from Russian plants, an example of which is presented in the series itself.
The whole documentary tells us how we got here, the how's and why's the war in Ukraine started, because like so many things, you have to know the history of a thing to truly understand it.
I, as someone born when the Cold War was starting to thaw, didn't see much of it in my life. I had read about it, I'd had seen what media was created because of it (both directly and indirectly), but learning about it from people who lived it was very important. There were many things I didn't know that this doc taught me.
I highly recommend this to everyone, no matter your age....but the conservatives will whine about how this is all "fake news".
