While we all know that The Tragedy of Macbeth is based on Shakespeare's play, Macbeth, this film is a play. For anyone who knows the story of Macbeth well and has a deep care for its language, this film is exactly how you'd want it portrayed on screen.
And by "anyone who knows the story of Macbeth well and has a deep care for its language," I am speaking directly to my high school English teacher, who read the play to us in such a way that it made learning the story exciting and not as tough as others have described.
It seems like that's the block for some people when it comes to Shakespeare: it seems boring, there are too many pages, the words don't make sense, it's too confusing, etc. And most of the time reading Shakespeare, that was the case for me. The Tragedy of Macbeth captures the essence of Macbeth but does so without clutter (or an impending test); it's able to remove all of the distractions and allows you to focus on the story.
The background of each shot practically doesn't matter: in expansive, blank rooms with minimal furniture. Our eyes and focus are on what's most important: the characters and their words. The sharp contrast of shooting in black and white adds further to the ominous nature of things. Stark and serious, every sound seems to carry, from each character's voice to simple drops of blood that become a drum beat. These elements allow the movie to feel like less of a film and more like a play, and it's carried out so as not to feel outright.
And that's without mentioning the acting.
