Ignore the naysayers. This is a beautiful, deeply sad, elegant, and poetic film from one of the greatest filmmakers working today, Terence Davies. Many here are dismissing this film as "catty", "stereotypical", etc. It's not in the least. It's a film based on the life of Siegfried Sassoon, a real UK poet who served in WW1 with Wilfred Owen, the brilliant soldier who wrote the poetry that was the basis for Benjamin Britten's magnificent War Requiem and who was a friend/lover of Sassoon. Sasson was a poet himself, an artist, and like all artists, felt alienated throughout his life from the world he lived in. We see that art world from behind the curtain, and anyone who has ever worked, or been privvy to, the behind the scenes of the artistic world will attest this is how it is. This is the huge source of Sassoon's "alienation", not just that he's a homosexual, which many reviewers are insisting. There's a wonderful line that sums him up perfectly, and that is "most people live in the moment. You want to live in eternity". That's a beautiful, poetic summation not only of Sassoon's life, but of art in general. Davies's films often draw on art for their inspiration, and this one is no exception.
All of the performances are 1st rate, the cinematography is exquisite, the production design is breath taking, and the dialogue is some of the best I've heard in a film in a very, very long time. Thanks to Mr. Terence Davies for making such an extraordinary movie.
