Why is Lighthouse the Best Movie in 2019?

Robert Eggers creates "The Lighthouse", his second project, which has already become notable. From popular scales to an unusual format, he sorts through mountains of historical documents and works with sound engineers and costume designers down to the smallest details, such as buttons. The film is considered the best movie of 2019, and the question is why it stands out and why Eggers was nominated for an Academy Award in the Best Supporting Work category.
