I saw it last night and thought it was stunning. The cinematography was out of this world and some of the scenes I thought took your breath away. It was far from the typical war movie but reminded me a bit of Apocalypse Now in the dreamlike feel of some of the scenes and the way that the set pieces transitioned. That burning French town sequence through to the waterfalls was unreal ! People have accused this film of being unemotional but I thought it packed, in its way, a considerable punch. Like the lack of forced sentimentality too.
I thought that there was a sort of very familiar look to the scenery around that ruined farmhouse then read that it was actually filmed on the chalk downs North of Salisbury, Wilts ! Ironic, as the WW1 army used to practice around there before being sent into action across the channel. Much of the scenery seems to have made use of the UK - even the white water rapids.
Obviously influenced by Tolkien’s books too, in the use of repeating motifs/allegories, ‘way station’ helpers such as the various army officers en route and the ‘mission’ focussing on command instructions in place of the ring. So - a mix of the real and the mythic.
Definitely one to see on a large cinema screen with a good sound system.
