There's bound to be spoilers in a thread on a film, so I'd suggest if you haven't seen it yet, then skip this.
Shutter Island's supporting cast of Mark Ruffalo, Ben Kingsley, and Max Von Sydow was enough for me to watch and it turned out to be worthy of the Conspiracy Therapist second highest rating of 4½ stars. Some of the best scenes in the film are simply expository vignettes on declassified CIA mind control programs involving drugs and ex-Nazi's with an added bonus of the infamous icepick lobotomy thrown in for good measure. Can't let the psychiatrists get off scot-free. Scorsese did have the balls to allow DiCaprio's character to ask a very pointed question to its American audience at the end of the film, one that has long since been answered, but perhaps Scorsese thinks will be reconsidered.
The most interesting thing about the movie is not it's Magus-esque (recently applauded here) 'Which-level-of-reality-is-mind-warping-me-now?' plot, but comparing Shutter Island to the Robert DeNiro directed The Good Shepherd (2006), which covers some of the same ground regarding how deeply the CIA has penetrated our society. DeNiro looks even better now.
