"The Lighthouse" is a stylish portrayal of descent to madness without plot or point. It is classified as a thriller and seems to have all the pieces of a thriller except the fact that there is (a) no real conclusion, and (b) no real point to it all. The story is limited (2 guys going about their work at a secluded lighthouse island), the characters are limited (crusty seafarer and seeking wanderer tropes) going about their business. Sprinkle in a few weird things which escalate to more and more intense conflict (sort of...fighting one minute and hugging the next) and confusion. Nice cinematography though.
