I was also in France at the time when viewing the movie, it was very surreal in so many ways to be empathizing for a protagonist on one of the enemy sides - from an American perspective as I am an American.
But I had never seen anything depicted about that war decades before the US got involved.
I had never seen a war movie produced outside of Hollywood. Or a director with primarily french influences producing a war movie.
It was sensual, horrific, erotic, fascinating. I dont think it would get greenlit by American studios. Maybe some streaming services have it though.
