Paul Elliott’s review published on Letterboxd:
This psychological horror from Robert Eggers (The Witch), set in the late 1800s and beautifully shot in grainy black and white, is powerful, brilliantly cinematic, and also genuinely humorous in places. It follows two lighthouse keepers, astonishingly portrayed by Robert Pattinson and Willem Dafoe. They both deserve universal acclaim for their performances, as they confront the isolation of both the deserted island and the Lighthouse. Eggers takes advantage of a variety of things to consistently grind down the characters such as miserable weather conditions and native avian menaces while locking the men together in their tight confines.
The second act of the movie commences a tour de force nosedive into degradation as reality starts to slide away as time becomes outwardly infinite, and it’s here that the director grants his actors a podium to display their incredible talents. Their descending trajectory takes on many manifestations along the way as secrets are exposed, and the crushing seclusion strips away their soundness of mind. The Lighthouse is a darkly atmospheric descent into absolute insanity.
