I think you are conflating Malick's naturalism with the total thematic ends of his films. Make no mistake: The Thin Red Line is a film about the internal effects of war. His naturalism ties into this theme and is the theoretical and aesthetic apparatus by which he explores this theme, but the film is not asking the very same questions as Badlands or Days of Heaven. What Malick brings to his films better amounts to a kind of sensibility or an attitude rather than a loaded body of conclusions about the subject matter and content.Quoting Irish (view post)
Malick's naturalism, for instance, doesn't unearth The New World of its more direct meanings and implications. It grounds them. It's for this fact that the film is more, and not less, about the Western man's insatiatiable quixotic ambitions of possessing foreign lands and "new worlds," even when at the expense of his own self-destruction. This is a film that attempts to reconcile man's ego, his expectations, and the limits of his will with the unassailable scope and complexity of the world. As he does in his other films, Malick approaches this theme with delicacy, earnestness, and calm, without judgment and undue scorn or outrage (unlike Herzog). He doesn't criticize man's idealistic project of enlightenment and quest for colonization so much as he at once admires its limitless passion and pities its unwitting niavety.
This is not a man who makes the same movie over and over. The charge really belongs elsewhere.
