IMO the peak of the movie was halfway through when Blake was killed off. The entire first half of the film is brilliant. Following both of them really captured the gritty, horrifying aspects of World War I. While it was a BOLD move to kill off Blake, and the scene is arguably the highlight of the film, surprising, and perfectly captured visually and by the actors, it also leaves the 2nd half of the film in a very difficult position since the tracking shots are now following just one character. This IMO took away all the suspense and edge from the film. Again IMO, I did not feel that Schofield was ever in danger of dying in the 2nd half of the film so he is the lone character left and we are just following him. There are 5 moments in the 2nd half where he just narrowly escapes death: The first is the sniper scene where he's walking on the beam across the river. 4-5 bullets narrowly miss him. The visuals of this is outstanding but I was sitting there totally fine never expecting him to die. The next is after he wakes from unconsciousness he walks into the town which was BEAUTIFULLY portrayed on screen with the flares lighting up the sky. He sees a German in the distance who charges him and hipfires at him narrowly missing him. Again, never thought for a second he was in danger of death.
He then enters the basement of I believe the church where he encounters the woman and the girl. I personally felt this to be out of place and unnecessary. I thought the scene was in place to humanize him and display that all those involved in war aren't bad, and in this case, he had no choice but to be there and was a good person. However, to me, this was just a break from everything going on and unneeded. There are multiple examples of him being a decent guy and rather innocent guy. It's displayed throughout the film when he initially questions the decision to deliver the message, to helping the German pilot that kills Blake, to not immediately killing the German soldier he encounters later in the film. I don't know, just felt it unnecessary and out of place.
After this he gets chased again, bunch of bullets missing him. He takes a full leap into a river which then conveniently perfectly carries him to exactly where he's supposed to be. He gets out, struggles to find where he's supposed to be, narrowly avoids being blown to shreds multiple times, delivers the message, and he saves the day. Then he finds Blake's brother in the middle of mayhem.
The 2nd half of the film was just too neat, too perfect. I saw a review where it felt structured like an adventure video game where you have a bunch of fun chase scenes, narrowly avoiding death, and then are the hero in the end overcoming a bunch of improbable odds. I agree with that. The 2nd half of the film to me really suffered from plot armor and at least from this one person in the audience (me) never believing he was actually in danger.
It was mentioned at one point in the film how Schofield should have witnesses when he delivers the message. I thought an ending which would have encompassed the atrocity and brutality of World War I and giving the film it's edge back, would've been for Schofield to have delivered the message and it was too late and they were all massacred, or the captain just defying orders and sending everyone to their death. Maybe I'm just a piece of shit but the 2nd half of the film was just too 'perfect' to me and my vocab isn't strong enough to explain it better than that.
