Oh I was about to watch Fight Club again, sad to hear that it didn't age well.

I can't see it as anything now except foreshadowing of the emergence of radical fascist brown shirt gangs into the semi-mainstream.

I think there are things about it that still work, like the scene where the narrator breaks down how recalls work. And, especially, the meet-cute where the narrator makes the "single-serving friend" joke, and Durden replies "That's very clever. How's that working out for you, being clever?" I think that's one of the best lines in a movie ever.
