This is one of the most brilliant movies I've seen in a long time. I understand why some people might not fully appreciate the story (which reminds me of Aronofsky's Black Swan in that it's a painfully slow descent into Hell). I find this film as complex as a fine scotch, or a fine wine. The top note is, of course, the beautiful visuals created by Ben Davis. The acting all around is phenomenal. Farrell and Gleeson were, of course, nothing short of spectacular. The real surprise was the character created by Barry Keoghan. I couldn't help but be amazed by how real his character was. Although I was expecting the banshees to be like in the horror film I saw as a kid, I really appreciated the Shakespearean witch device. It was perfect in this context. The second note of flavor of this masterpiece is all about relationships in a closed community. If you ever lived in a condo, an association community or the like, you will recognize the day-to-day pettiness that everyone thinks is so important. A subtle addition to the complex layers of flavor is Burwell's perfect score. And the deep flavor of this movie? It is the parallel that the protagonists finally draw to the meaninglessness of the Civil War that rages on the mainland. If two people within a single tribe cannot make a peace, how is this poor world ever going to live?
