The Sixth Sense starring Bruce Willis and Haley Joel Osment was one of the most popular movies of 1999 and was a launching point for M Night Shyamalan’s twist-ending based career. The movie follows Malcolm Taylor, a totally alive child psychologist that’s trying to help Cole Sear, a little boy with the ability to see dead people. The film was a cultural phenomenon, but it definitely raises a lot of questions. Like what exactly ARE the rules of being a ghost in this world? Why do they only seem to apply to Malcolm? Why are all the ghosts so hostile towards Cole if they actually just want to talk? How is Cole going to help ghosts that don’t have currently active easy-to-solve cases? Does this whole movie just exist as a set-up for the big twist ending? (thetvdb.com)
