As a previous reviewer has stated, the documentary starts out with a curt two or three sentence summation of how the war started. This is unfortunate because after watching "37 Days" a few days ago (a mini-series on the 37 days that led up to the war) it is quite an interesting story.
The rest of the documentary focuses almost solely on social changes that the war brought. It never really mentions any other country that was fighting with it, their relationship, how the decisions of one country effected another, etc. There was no mention of art, poetry, songs that were written, or anything of that sort, even though it was "vast." I only say "vast" and use it in my title because the narrator uses the word constantly. It gets annoying.
If an uneducated soul watched this documentary you would that Britain won the war on its own. No mention of Australians or Canadians until after the war is over and they "took to Trafalgar Square and lit a bonfire." Not one mention of America or Russia (Russia lost more men than any other country fighting the Nazis, it is worth at least a mention, no?).
They treat the sinking of the Lusitania as if nuns were aboard, instead of munitions. And they forget to mention that she was breaking international "Cruise Rules" by doing so, and was therefore fair game for the Germans.
It also speaks of the rich going off to war as if they had more to lose and therefore were more of a hero than a poor person enlisting. It also mentions that the rich kids became the leaders automatically and that it was somehow "bad" because they had a higher death rate. Maybe they had a higher death rate because they were soft and weak, who knows? It also said the poor were much better off for the war because they were given "meat every day." Like it was some sort of charity and that poor people should be grateful for being shot at.
And then it ended. Just "and finally after four years, the war ended." It seemed sudden.
Overall, not that great.
