This I struggle with because in that case favorite movie of all time, Casablanca, would have to be on this list. Just not sure they are "war" movies.
Patriot had to have been written by a twelve year old. My grandfather, who was actually in a war, said Saving Private Ryan was the best he’d seen.
My dad is dead and he never never got to see a lot of these movies, but this is still what he would say.
