You have to be in the right frame of mind for this. It isn't a heroic epic where everything turns out all right.

It is a graphic and real depiction of the horrors of war from the eyes of those fighting on the front lines in ww1. It is meant to make you question the motives of leaders. It is meant to make you think about how much the normal people putting their lives on the lines to kill each other, actually differ from the ones they are killing. And it's meant to show you/make you viscerally feel the shift that happens when you move from only hearing the media/govt rhetoric - to seeing first hand the conflicts of interest / cruelty in your own / illogical decisions - to finally becoming a numb, automaton following orders blindly to stay alive.

It is a very well made film. You care about the characters. You feel the emotions. You really understand the implications of the fruitless efforts at the western front. You end feeling how tragic it was. I ended feeling anger for how people were treated like throwaway chess pieces. You've got to be in the right frame of mind!
