For a movie to come to be considered a "classic" is no mean feat, and I will argue that David Fincher's Fight Club (1999) is one such film.
Every classic film's themes are relatable and timeless. Lesser movies are ridiculous period pieces that never hold up because. people are sure to look back at The Last Jedi, for example, and say, "Third wave feminism and patriarchy were a thing? Boring!"
Fight Club warns of the danger of trying to control human nature.
And, no, the movie is not "anti capitalism," as some have argued.
If you take it literally, you won’t like it. I suggest watching it again after you discover the Narrator and Tyler are one in the same and bear in mind that Fight Club isn’t actually about fighting.
Of course, I liked “In The Valley of Elah”, being a Tommy Lee Jones fan (Elmer Kelton’s, “The Good Ol Boys”, “No Country For Old Men”, “The Missing”,etc.) I saw Jones’ character Hank as sympathetic to the military, lost and foundering maybe, but still polishing his shoes and marching along…and heartbroken. That bit at the end with the flag tears me up every time I watch it. I didn’t see the movie as a strike against American exceptionalism or the military…then.
