Nosferatu
I was honestly surprised how the movie played out for me on second viewing. For me personally I thought it was much scarier and grossed me out more on the rewatch. I was also able to enjoy the little things much more, without having to think about the bigger story as I already knew what was going to happen.
The whole film has so much sauce with the camera work and the cinematography I thought it was easily one of the best looking movies of the year.
