8. Fight Club
To preface, there is a backstory for Fight Club and I. I watched it late in the game, after everyone told me how amazing it was. So expectations were high. As I sat down to watch it with my wife, then girlfriend, who was forcing me to finally see it, I jokingly blurted, "This isn't one of those movies where it's all in the guys head is it?" She looked at me in utter silence. I'd guessed the ending before we even hit play. But the film was great and I loved it anyway. But more importantly what I appreciated about it was the knowledge that it was one of the early players in the, "it's all in the guys head" twist phase. There was a solid five years where every other thriller coming out was a film where the twist was that it was all in someone's head. It felt tired, old, and stupid after a while. But when you saw that ending for the first time, it blew you away. Fight Club earns praise because it was one of the first to have such a strange ending, regardless of whether or not I had seen it when I should have. When people first saw Fight Club, the guy inside a guy ending was weird as hell, new, and very cool. The fact that Norton had such a drastically different split personality and that the movie was orchestrated so well as to allow little reason to suspect Tyler Durden as being inside his mind and that this part of his personality had been so meticulous as to set up fail-safes to ensure his plan would proceed, is all pretty mind blowing.
