Eli Crowhurst’s review published on Letterboxd:
Writing a review for a movie like this is incredibly hard. This is a rare case where the best thing I could say is I need to have someone explain the film to me, though that may not be a bad thing.
The Lighthouse is a love letter to the theatre of the absurd and classical movie making and human nature.
Okay, so that doesn't make a lot of sense, but neither does the movie. I found that to be what I enjoyed most about it. It is marketed as a thriller or a very dark comedy thriller, and that's fine but doesn't do the film justice.
I believe the correct way to describe the film is 'absurdist cinema.' By its nature, 'Absurdist cinema' is challenging to describe. Absurd stories are less about the story it's telling and more about the experience of the audience. This is why a lot of critics will praise this movie who have been critics for a very long time, but a casual moviegoer wouldn't or at least like myself would have trouble expressing our opinions of the movie.
So should you see this movie... Yes, but you don't have to. This is a film for movie lovers and creators. It's a deconstruction of boredom and mystery. The film tends to go out of its way to say that the timeline of events doesn't matter because the characters don't even know. It's very similar to Samuel Beckett's play 'Waiting for Godot,' a play that has been deemed the play which nothing happens.
However, things do happen in The Lighthouse, but it's more about what's happening with no consideration into why it's happening in the first place.
The film raises many questions and answers none. It's smart, dark, funny, disturbing, and an engaging movie to watch. Go into this movie with the expectation to be surprised, and you'll have a blast.
