Two men assume their month-long duties to tend a lighthouse, but madness starts to set in.
Shooting in B&W worked great for this film, not only for the time period it took place in, but with the overall feel of the film. Same with the aspect ratio. Seeing as how there were only (for 99% of the film) two characters, it made it feel more personal.
Not positive exactly what the film was about. It was either Ephraim going insane, Ephraim already insane, or we were seeing two different sides of the same person.
One of those movies that doesn't wrap everything up in a nice package and hand it to you. Which I really enjoy, because it's fun to get challenged and have to think.
