Let me start by saying this is a very good movie, just not great, and I will try to explain my point of view... I went to watch this movie with some high expectations, seeking a quality as good as "Hacksaw Ridge (2016)". It was not reached. The cinematic experience of a "one shot" movie that Sam Mendes tried to give made me, at some points, bored of it. There's a lot of unnecessary moments portrayed at the movie, such as going through the trenches, because Sam Mendes did not achieved a quality script to fill the 2h lenght of the movie. Sam Mendes said in a interview that he wanted to give the experience of 2 "real time" hours, but the development of the story is clearly more than that. I yawned while seeing at the cinema... And I was not tired. The moments of suspense/ thriller/ action don't overcome the rest of the movie. If I made a homage like this, I would like people to tell me the truth and not sympathize with it just because... The acting was very good and I enjoyed that Sam Mendes didn't gave the main characters to Hollywood stars. George MacKay and Dean-Charles Chapman made a great work My honest rating for this movie is a 7.4.
