There are very few films glorifying the first world war, called the "Great War" by those who fought and lived through it. If anything, Hollywood has avoided the subject and left it to a few European filmmakers, for very good reason. For sheer carnage, nothing has surpassed it. The slaughter of very young men was truly appalling. One can only imagine the reaction today if 50,000 men were dying each month to hold or advance over 100 yards of desolate mud. I went to school in England where the walls of our classroom were covered with the photos of pupils who had died in the war. Mostly aged 17. It was not until much later that I realised why there were so many unmarried middle aged women around in the 50's, when the writer Dr. Phyllis Bentley explained that there was no one for them to marry. An entire generation of men had been wiped out.
Regeneration is a thoughtful anti-war film where the paradox of war is implied in a Scottish hospital for the treatment of shell shocked officers. The doctor has to get them well so they can be returned to the front lines, where they will more than likely be killed. The script is intelligent and the acting is superb. There are some allegorical scenes which do more to underscore the pigheaded arrogant mentality of the "establishment" which continued a war until quite simply, there was no one left to fight. Even sick men with TB were sent off to fight. Perhaps the saddest aspect of watching this film is when you realize that WWII began 21 years after the first once ended, just long enough for the new generation of soldiers to grow up.
