Dunkirk, starring Hans Zimmer.
I came in expecting something like Interstellar and left with something entirely different. The movie has actors and characters, but they pale in comparison to the concepts of home, war, and the music of Hans Zimmer -- they are the real characters of the film. From the beginning of the film you are thrown into a world of survival and until the ticking stops you are constantly clawing your way to safety. The multiple timelines disorient you at the beginning and until the shell shock wears off you are just trying to make sense of where you are in the film.
This film will not be as accessible to the general viewing public as Interstellar and I hope people don't go into it thinking, "Director of Dark Knight? Of course I'm going to like it!" The film reminded me a lot of Soviet montage theory. Space and time is pretty much disregarded and the music and larger concepts carry you through the film.
