It's satire - it's making fun of the protagonists as much as it's commenting on them. Ferris bueller doesn't strike me as satire in the same way.
The whole Fight Club and later Project Mayhem id a complex digression he invents to avoid facing the fact that he wants to get close to Marla.
the destruction that follows from his desperate avoidance of this relationship nearly results in his own castration. his last gasp at being an independent man threatens his very manhood. damn.
The vibrator in his suitcase? No accident, just there when he was Marta.
Note the ending when they're hand in hand, they look identical.
I'm not doing the critique justice, but I found it compelling enough to remember it and share it here.
