Consequently, thrillers are often guaranteed to feature mind-bending plot twists.

The Shutter Island ending is still debated and discussed among fans and critics more than a decade after the movie was released. Martin Scorsese directs the period thriller in which Leonardo DiCaprio plays Tedd Daniels, a US Marshal investigating the disappearance of an inmate from a psychiatric facility on the titular island.
