Willem Dafoe repeatedly gas-lighting Robert Pattinson is hilarious and maddening. As a matter of fact, everything is maddening, from the aggressive gulls to the farts to the isolation to the constant gas-lighting.
It's impossible to imagine anyone but Willem Dafoe playing that role. Everything about him - face, voice, how he carries himself - is perfect for it. Robert Pattinson is great as well.
The Melville inspired dialogue is beautiful and horrible.
I preferred The Witch slightly, but I'll keep watching anything Robert Eggers makes.
