Creative plagiarism = new idea

If you think Shutter Island ripped off Identity, then you should also watch Twilight Zone 1985 Season 1 Episode 56 - Shadow Play.
What's good about Identity or other movies with new adaptation is that it puts in new theories and thus became a new movie.
This psychological/psychoanalytical thriller is not a new genre, but definitely a comeback trend according to recent releases.
For those enjoy this genre, I would recommend a few classics: -Psycho(1960)
-Sybil (1976)
-Angel Heart (1987) (re-make coming up)
-American Psycho (2000) -Machinist (2004)
-Psychiatry: An Industry of Death (2006)
-A Mulher Invisível (2009) (English Title: The Invisible Woman)
-À la folie...pas du tout (2002) (Eng Title: He loves me, He loves me not)
-Lucía yel sexo (2001) (Eng Title: Sex & Lucia)
All these movies visualize our psychic - brings you down the rabbit hole so to speak. That's the best way I could put it. Enjoy ~
