The Diagnostic and Statistical Manual of Mental Disorders defines multiple personalities as "the existence within an individual of two or more distinct personalities, each dominant at a given time. These personalities are independent and autonomous from each other. and exist as a complete self". Marie's subject personality and object personality obviously produce irreconcilable contradictions, so her behavior is abnormal, and her thinking diverges to the point of being out of control. Such killing truly shows an instinct that exists in the human subconscious: fighting for love. You can't say it's bad because it's a lesion. If it is good, but she uses the subconscious as a carrier to show her truest side with violent crimes. Looking at this case from a scientific point of view, you will also find it very difficult, because most of the time, even psychiatrists cannot explain this phenomenon. After all, the head grows on other people's necks, and we don't know how to think. Here, I call multiple personalities: double body.
I noticed a few of Marie's smiles, typically neurotic. The actor played this nuance so vividly, it has to be said to be the finishing touch. The film creates a suffocating effect, especially when Marie wipes the water stains in the bathroom to avoid the "mysterious killer", hides the sheets under the bed, hides in the shutter door closet to witness the killing process, Hiding under the supermarket shelves at the gas station, having nowhere to hide in the men's toilet, etc., all expand the atmosphere of fear. I don't know how other people feel, but I think it looks good, because that heart-wrenching tragic ending deeply touched my heart.
