Thomas Shey
Legend
He isn’t satirizing the book. He is satirizing militarism and fascism and using the book as a starting point. I think what happened was he signed on to direct but when he started reading the book he disliked the message so much he put it down and decided to make a film with the opposite message. But there is no real rule that a movie has to be an accurate depiction of the book. He is using it as a starting point, not trying to give people a synopsis. One benefit is people who haven’t read the book before, when they read it will find many aspects surprising. Obviously not every one has to like the movie or agree it is good satire. But I think the complaint that it changes characters isn’t a very strong one (Voerhoven didn’t even finish the book, so I don’t think he had any goal of staying true to the characters (he or the screenwriter even changes the sex of a major character which has major changes on the story)
I'm afraid I don't buy it. The scene I'm referencing is too close to the one in the book not to be deliberate, but he deliberately twists it to support his agenda.
An anti-militarism parody of ST is a valid concept. You can argue that to some degree that describes The Forever War. But when people go to see a movie with the name of a book, that seems on at least cursory examination of the advertising to be based on same, I expect it to at least attempt to capture some of the concepts of themes of same. Otherwise do a new work.
