Personal Shopper - The Criterion Collection (Blu-ray)

A personal shopper for a celebrity in Paris — who also works as a medium trying to contact her recently deceased twin brother — begins receiving mysterious text messages that may or may not be from beyond the grave. Olivier Assayas's slippery, formally inventive thriller — starring Kristen Stewart in a career-best performance — refuses to resolve into either ghost story or psychological portrait, remaining permanently, productively unsettling.
