Embodiment of true love

Rachel has issues. She's alcoholic, she's got temper, she's depressed and sad because her ex-husband has a new family. She becomes obsessed with the disappearance of a young woman she's spied out of jealousy before. Emily Blunt is terrific as the crazy drunken person who is afraid of herself. And there are some truly disgusting features that are almost too nauseating to watch, hence a pretty unforgettable film.
