I never finished the movie until I read the trivia

Rating: 10/10 (4 January 2016)

The movie turned out to be a huge surprise. I thought it was another Woody-Allen-style gloomy movie about a loser going through his mid-life crisis by understanding some philosophy that doesn't make sense in real life. But it isn't. As the movie unfold, I gradually noticed that every shot was precisely calculated, every object in the frame symbolizes something. Fight Club is more than what it seems like.
The CG is amazing. With the swooshing audio effect, the sense of reality is as compelling as it can be. It's especially astonishing to understand that the opening CG is actually the biochemical reactions happening in the narrator when his hallucination is pointing a gun at himself. I could hear myself breathing when he told Tyler "The gun is not in your hand, it's in my hand." He realized the existence of Tyler is a hallucination. But like any schizophrenia patient or dissociative disorder patient, he couldn't put off the hallucination like "puff" and go on with his life. The only way to stop Tyler is to kill him, which is to kill himself.
However, if he becomes aware of his own mental illness, he should've go to a psychiatrist instead of a police station(full of terrorists). Because what's different from other schizophrenia patients is, Tyler Durden is trying to alter the narrator's identity, reforming him into another person. Instead of giving him paranoia like in Beautiful Mind, or give him horrifying visions like in Black Swan, Tyler is an outburst of this loser's potential, and this powerful figure is trying to replace the body's former owner. The mere thought of it gives me a shiver.
There are numerous suggestions of the two leading roles being actually one person. We don't know our protagonist's name, for the start. On airplane, Tyler opened his suitcase but the narrator didn't open his. He received a call from a booth with a "no income calls allowed" sign. When he hit himself in front of his boss, he said: "This reminds me with the first time I met Tyler". When Tyler was hit by Lou in the basement of Lou's bar, the narrator seemingly received some impact simultaneously... Although it sounds like a absurd fairytale, this salary man started a terrorist attack without even aware of it.
Although due to false advertisement and too obscure cues, this movie hasn't received the credit it deserves, Fight Club has become my favorite movie and David Fincher my favorite director.
