I watched the show, I loved it, it wasn't 100% depressing or propaganda, it was reality I'd say, because most of it is very much likely to be true, I have yet to finish watching Anatoly Dyatlovs interview but the show I would definitely recommend, it is not too sad, it has it's moments of good laughter, but it's a serious one and has some gore, very explicit and realistic gore, so if you have a soft stomach I suggest try and skip some of those scenes, but altogether it is a fantastic piece of art.
