As far as I can tell the message of the movie is "consumerism is bad because it's emasculating and feminizing, real liberation can be found in ruthless hierarchies of masculine violence"
The only person I know who likes it IRL also has a tendency to complain about the "pussification of modern men"
Yo I'm drunk, so I'm not going to give a serious answer with any political or social analysis.
First of all, I'd like to say "just see the movie." Steal it! if you find it chuddy, delete it! I will say that there are some works of art that can be appreciated despite their politics, and while art may be inherently political, you shouldn't be relying on it for your politics anyway. Life is hell, art can be a sublime escape.
It's a cool movie. Ed Norton's great, Helena Bonham Carter's great, Brad Pitt is great (and shirtless while being so very lean and cut). It's not that strange of a film, but still, but it wouldn't get produced today with the same production level, so it's kind of a relic. If you like violence, you get to see Jared Leto get his face caved in. If the fantasy of sticking it to your boss and robbing the company appeals to you, it's got a scene for that. wanna fantasize about forming a revolutionary group that does acts of sabotage and violence? This movie might appeal to you.
for what it's worth, chuds have terrible art comprehension skills, they miss out on things like irony, subtext, and hypocrisy. A chud might like Star Wars and then get angry if you point out that Ewoks are like the Viet Cong.
