I know I have a soft spot for military/military related movies being a veteran and coming from a military family so I may be biased but if y’all don’t mind an older movie check out The Best Years of our Lives. It came out in 1946 and is about 3 guys from the same town returning home after WW2 and picking up where they left off.
It may sound like a boring premise but I promise it’s an excellent movie. I know it’s currently available on Pluto TV.
The sad truth is that most people now cannot adapt to old black-and-white filmography no matter the topic or grandeur. People now just will not tolerate reruns of old B&W movies - they're too drab, too slow, too tedious to unfold.
Outside of the exotic film noir genre, there is no current audience for B&W movies.
Many of my favorite movies are in black-and-white. What I dislike is modern movies that are in black-and-white, just because. I think these movies are almost always worse because of it, and that it's a crappy decision for a director to make.
