Overpraised like Dunkirk. All the time you just hear (or read) that the movie was made with an one shot approach/method but this is just a technical question and makes no good movie itself. Compared to Paths of Glory (1957) or All Quiet on the Western Front (1930) this is not much better (regarding being realistic) like Emmerich's Midway or Michael Bay's Pearl Harbor, but those at least got some fine and epic action scenes. All in all: a big Hollywood production with every possible war cliche you can conjure up. Also the sounddesign (drones, ambient noises and melodies) does not fit into the movie at all - and where is the sound of heavy artillery that you can hear for many miles!? To sum it up: no masterpiece, but mildly entertaining.
