This film depicts abnormal psychology in a deeper way that most mainstream psychology-based thrillers/dramas totally miss. The horror isn't shoved down your throat, instead it relies on your own empathy to put yourself in the main character's mindset and once you're there, it's very unsettling. It's easy to feel like your mind is spiraling out of control. The overall look and feel along with music accentuate this feeling and turn the film into a totally immersive experience. The slowness at the beginning and little bits of comic relief ease you into a sense of relatable familiarity before taking your mind to very unsettling places. This movie isn't supposed to make you feel comfortable or amused, it's more like a mental trip, pushing the limits for what the average person is willing to relate to and empathize with. There are some awkward moments here and there, but if you stick with it, they add to the experience overall.
