One shot gimmick of the movie seriously undermines the potential of the movie. Instead of normal immersive feeling of a good movie, you get what feels like on the rails trip following two soldiers on their way from point A to point B. This ride along feels very planned and convenient, seriously lacking organic touches of good story telling.

There are also few too many modern cliche's that erode the historical authenticity of the movie. Also for WW1 war movie, the whole thing just comes of as way too clean.

Movie as whole is not that bad but definitely not worth the hype it is getting.
