Watching this movie was an intense experience. I don't quite know how to effectively describe the degree of uneasiness I felt. At times it was so unnerving that I had to completely shut down emotionally . You know how when everything around you is beyond your control and your mind goes into flight mode? That.... that's the feeling that explains the effect this movie had on me.It's the same kind of anxiety and hopelessness you feel when watching midsommar. Just imagining being cut off from normal ,healthy, well adjusted people for such a long time, surrounded by the ocean which is an unpredictable, vast , boundless chasm of hidden danger is nerve wracking enough. But to be trapped in a downtrodden lighthouse surrounded by all that with only a flatulent old man for company ,who barks orders at you and forces you to do strenuous work without offering you the least bit of encouragement or neary a kind word , while having to gulp down unappetizing food and fending off seagulls that seem to have acquired a taste for human flesh is nightmarish. The worst part is young tom cant stand up for himself for fear of being fired. He is powerless and because of his past completely out of options and at the mercy of old tom. That feeling of powerlessness engulfs you.Maybe a human with a clean slate and clear conscience would have been able to survive this arduous task but sadly that's not the movie you will watch. What was so eerie was when I couldn't figure out who was the mad one. Up until that point I consoled my mind, lied to myself, convincing myself that I know who's crazy. But then theres this moment where you will place yourself in young Tom's shoes and you start to wonder if you're crazy or, and this is more horrifying, if you're stuck with a mad man who is lying to you and purposefully making you question your sanity for some hidden reason, and makes you think that he purposefully made the two of you hungover so that you would miss the boat for an unknown spine tingling reason, which is the only way of escaping into normalcy. At that point a feeling of despair washes over you, seeping through every crack of your being. That is what's so terrifying about this film. Watching this movie made me feel like I was kidnapped by a serial killer and trapped in his basement , and then one day I had a chance to escape, to have contact with normal people who could SAVE me but I was caught at that exact moment and dragged back into that basement to be locked away forever with regret and sadness and hopelessness filling me up, with only my quickly fleeting sanity to hold on to.I thought everything was wonderfully weird in this film. William Defoe and Robert Pattinson were robbed of their oscar nominations.
