This plot twist in Fight Club is truly one of the best in film history, though I only discovered it after watching the movie. Although the conflict between Tyler Durden and the narrator is visible on the surface, at the end of the day, it is clear that it was all about the emotional tension of one person. In my opinion, the subtle hint of the apartment explosion and Tyler's abandoned house that you mentioned doesn't really play in your head when you first watch it. Even though it was an experience watching on YouTube on your mobile, you captured the real message of the movie—anger against the system and a fight with your own psyche—very well. However, I think that the scene of the bank buildings collapsing after Tyler is shot near the ear at the very end was not only a symbol of destruction but also a strange liberation of regaining your lost self. In my opinion, this type of contest gives you a good idea about a movie you haven't seen, and getting a good idea about the movie increases your interest in watching it. Best of luck to you in this contest. 😊
