Fury (2014)

There are quite a few movies about World War II, American movies about the American experience in the war, European moves about the European experience in the war, and war crimes that occurred throughout the war.  The German army was one enormous moving war crime machine, and it turns out they were not alone in that. 
This is a gritty portrayal of Americans at war's end, moving through their enemy's country and literally flattening everything in their path, despite being under resourced and poorly equipped.  You can certainly argue that the story line is one that is well trodden at best, and gratuitous at worst.  The script was supposedly developed through interviews with WWII veterans who were in Europe after D-Day, looking back on how really terrible it is to still be a soldier when the outcome of the war is clear, but the enemy hasn't stopped fighting. 
There are a lot of lessons for us today, what with Navy seals committing war crimes and such, so it is well for us to remember that war is indeed hell.
