Rating: 9/10 (30 May 2011)

As far as plots go, Shutter Island is as full of depth and intricate as they come. An altogether intriguing story that centres on the dark happenings of an asylum-island solely dedicated to the incarceration and medication of society's most dangerous and disturbed criminals in post World War II Boston.
U.S. Marshal Teddy Daniels (Leonardo DiCaprio) is tasked to investigate the apparent disappearance of a housewife turned heinous murderess. With his own hidden agenda, he sets out on mind-meshing journey that takes him deep into an exploration of the black recesses of violent mental illness.
DiCaprio, expectedly, stuns in a role that seems to thoroughly consume him, and those around him – groomed actors who show themselves here to have mastered their own individual art – further serve to heighten the spectacular tension.
Directorially genius; plot intensive this is a film far above par. A definite must-see.
Excellent.
Where can I find the book?
