Would you watch a movie about this?

I am just curious if you would be interest in watching a movie about this. The movie would be about boy soldiers in the first world war. It would follow a group of friends aged 13-15 at the outbreak of WW1. The feel a sense of patriotism to their country and sign up to fight. The movie follows the boys from when the join up to fight in war and when they are on the battlefield. The movie shows the boys training to be soldiers and the hell they face while fighting. They see fellow soldiers die and being wounded. They have to deal with killing fellow men and trench warfare. What do you think of this being a movie?
