This is quite an harrowing documentary following a camera crew who secret themselves in a makeshift hospital in the Ukrainian city of Mariupol as the Russian military advances. What starts on day one as a largely intact and functioning urban area is gradually reduced to rubble as the invading forces bombard the place from the ground and the air slowly terrorising the populace and removing their access to even the most basic of necessities - shelter, water, electricity. It's told chronologically, and therefore it's quite easy for us to see the degradation day-by-day as the people somewhat stoically determine to stay put in the face of some pretty overwhelming military might. The fact that many people do stay is remarkably well captured here. Not just those living there, but those in the professional services who stay to tend the sick, put out the fires - their own sort of "Blitz Spirit". It's emotionally charged from the start and though there can be no denying it's propagandist nature at times, it still offers us an undeniable video-diary of the indiscriminate destruction of a city where - just like the V1 and V2 rockets - these explosives literally fall out of the sky and land where they may. There is clearly no "targeting" going on with the assault. The narration is just a little too softly spoken. Not that it needed Lord Olivier, but it was quite difficult to hear that was being described at times. In the end, I don't suppose that mattered too much for we can easily see what is going on. Ultimately, it also illustrates well the futility of this invasion. Whoever is left in control of this extended bomb site is unlikely to ever be able to make any use of it, or it's facilities, again. It's obliteration for the sake of it - purely as a show of strength intended to intimidate. This is a solid testament to courageous journalism that tugs at the heart strings, arouses anger and sympathy and though never an easy watch is well worth looking at.
