Maritime folk stories and sea-fairing tales have long been a fascination of mine, especially adventure classics like Ernest Hemingway’s “The Old Man and the Sea,” or Jules Verne’s “Twenty Thousand Leagues Under the Sea.” But Robert Egger’s 2019 nautical nightmare “The Lighthouse” has seemed to bring horror back into the ocean's shores. Here we have “The Damned,” an Irish and Icelandic period film that drips with salty terror and dread onto a fishing outpost in Iceland in the 1800s.
