The Sixth Sense hands down. Not my all-time favorite movie, but probably my all-time favorite cinematic experience, so perfectly shocked was I by the ending. I was lucky in that a friend called me and said, “Go see this movie, now!” And it happened to be playing at the theater in Park Slope near me, so I walked on over. Knew nothing about it, had seen no ads, didn’t know “I see dead people” or what it was about. And about 7/8 of the way through, I’m getting a little annoyed, I remember thinking, this is ok, but why on earth did he insist I see this? Like, I was ready to rip my friend a new one for wasting my evening. Then the ending happened, and the audience was stunned, and my jaw hit the floor, and we all walked out into the Brooklyn night, and I’m like looking to talk to someone, anyone, like, “Did you just see that?” Everyone was in shock.
An experience never to be duplicated.
