Shutter Island
As one of Scorcese's "minor" works, this stands out in his filmography. It doesn't even feel like a Scorcese. It really feels like a Nolan film. And in Nolan's filmography, this would also stand out as a mind-bender. I went into this knowing absolutely nothing, which is definitely the best way to go about it. Leo delivers a very Leo performance here, its great. He's tortured about his wife's death, something I think he's been able to do like 6 times.
There's obviously a twist ending, but it really is NOT what I was expecting that twist to be. And the ending really makes you think. I don't believe it's open ended, but I do think it's very disturbing. Also, I think we failed Mark Ruffalo. He was great in this and Zodiac and we made him dab as Professor Hulk.
This was a really engaging watch, and I'm interested to see what clues I'll pick up on on a rewatch.
