Shutter Island
For the first one hour of this movie it’s a normal police investigation of the seemingly corrupt director. However the second half is just a huge mindfuck. The show keeps us gripped with seemingly plot twist after plot twist. It’s highly methodical of keeping us confused right until the end. Very good acting and a great overall movie. The fact he regressed at the end again is another plot twist again. After which I’m assuming he got the lobotomy.
