In Personal Shopper (Blu-ray release 2017-4-18), the protagonist, proclaiming herself to be a medium, waits for a sign from his dead brother. Her job is to do the shopping for a celebrity. An unknown person texts her and seduces her to do the forbidden thing of wearing the clothes she acquired for her employer.
This movie gets mostly positive reviews, but I do not consider this psychological thriller to be thrilling, not one bit. Without any explanation, I do not understand how the protagonist could see and feel irrelevant ghosts but not her own dead brother. We see the personal shopper job being carried out for a significant amount of screen time, but much of it is not important to the main plot. I think the texting part is dumb – it is clear soon enough that the unknown person would not be her brother and there is no reason to fall prey to it.
