This encouraged me to watch more documentaries about Chernobyl I never realised how close we were to an even larger disaster. Shocking. Very well cast and acted. I was gripped. My only complaint was the accents. ....Yorkshire's Scouse, Midlands UK accents really took me out of it......I'd have rather they had russian accents or better still Russian with subtitles to get a genuine feel to it. But that's the only complaint. So one point off for that. Otherwise perfect.
