SHUTTER ISLAND - SPOILERS!!!
is the best made really bad movie in a long time. It reminds me of an M. Night Shyamalan, where everything is really interesting for most of the film until you find out the ending. The first two hours are really great. Very well shot, great score, great sound design, and then suddenly you find out that everything you have watched so far is complete bullshit. There's an inherent problem with a story that undoes everything you have believed and invested your emotions in for two hours. To completely undo the setup is really a slap in the face of the audience.
To make matters worse, there's another half-hour of the film left after this turnabout. I'd be willing to forgive many people for this filmic mistake, but Scorcese is a living genius of cinema, he really should have known better. In my head, I had written about a dozen better endings for the film by the time we get to the most obvious film school endings - IT WAS ALL A DREAM (or fantasy) - kicks the audience in the nuts.
I suppose this is worth watching for the technical work, but don't get your hopes up. Maybe you won't be as let down as I was.
