You can compare this WWO2 movie with the style of Dunkirk.
That means that the movie is not for everyone, but if you can appreciate this kind of movies, it's magnificent.
The movie doesn't want to be a hollywood blazing brainless action movie, but wants to portrait the germans on an individual level.
Like @barta-46978 says, the movie is about authority and gives yourself an insight in what it must have been at the time, and even how you would react in the given circumstances.
The movie is explicit and kind of shocking. It really intrigued me, we need more movies like this.
