The Sixth Sense is a 1999 Oscar Nominated Thriller written and directed by M. Night Shyamalan. The movie struck gold in the box office and is till date one of the best thrillers ever made!
The screenplay of the movie (available here) echoes its class as a top notch thriller. It has the right ingredients of a thriller… the perfect pace, the duality of writing and many other factors. By “duality of writing” I mean the ability of writing something that could mean a plethora of different things based on context of the viewer. In this case its mostly got to do with the perfect balance of what if the viewer knows the ending or not.
