Personal Shopper (2017)
A terrific surprise of a film. Had no expectations going in and really knew nothing about it, but this turned out to be a brilliantly effective ghost story that has you questioning what is going on in front of you while also not resorting to the tired and cliched aspects of the horror genre that have caused the genre to generally become stale these days.
Kristen Stewart is excellent as Maureen, the film's protagonist, who finds herself trying to make contact with her deceased brother after the two had made a pact that the first of the two of them to die (they both had the same genetic heart defect) would reach out from beyond the grave and attempt to make contact with the other. This is Kristen Stewart actually doing some acting, not moping her way through another Twilight film, and while she's turned in some quality performances at other times in her career, this should be the film that causes people to take notice of her talent and give her the due that has eluded her to this point in her career. The fear, sadness, paranoia, and the wide assortment of other emotions that Maureen goes through as she navigates her day job as a personal shopper for a fairly successful model as well as the potentially supernatural goings-on that happen and are caused by her as she tries to seek out the spirit of her deceased brother.
