I watched this movie last weekend, and though the cinematography is outstanding, I thought the movie too flawed to do justice to the book.
The makers seem to have just picked a few chapters from the book, the scènes filmed, I would, at very best describe as, "loosely based on".
Besides (to my taste) missing very many important bits of the original story, the entire film felt too neat/sculpted/styled.
I feel the movie lacks the total devestation and desolation that the book portrays.
The movie also displays a lack of understanding of 1916 to 1918 tactics/warfare.
Having read the book multiple times, I feel that the 1970's movie does it better justice.
