Where should I start? I managed 20 mins of this facile movie on Prime, a record seeing as I am a WW1 buff who's grandfather was a British officer in the trenches at the Battle of the Somme. Stilted acting, looked like a bunch of enactors who got together for the movie. But enactors would not have got fundamentals wrong. The 'Lt' wears no rank badges that should have been on his lower sleeves. Out of nowhere, a very elderly man in U. S corporal rank with upside down stripes appears as a "Captain". I mean, how can you get this wrong? I couldn't work out who was supposed to be U. S or British. Squeky clean Lee Enfield rifles, with a smattering of P1917 U. S rifles. Mixed up kit both U. S and British. British with U. S style button up collars amoungst correct flat lapel type correct for British in WW1. Modern Jerry cans lying on the battlefield. The rankless British 'Lt' carrying a Lee Enfield instead of side arm, possibly acceptable if going on a raid. Shiney reproduction helmets when they were not green they were khaki and covered with a springling of sand to stop reflection. It went on and on until I just had to switch off my Boxing Day feet up relax. Awful and ridiculous.
