Kristin Stewart and her cell phone co-star in “Personal Shopper,” a ghost story for the cyber age. Since Stewart always looks slightly haunted, you could almost say it’s typecasting.
However, the typecasting here is of a different sort. As she did in “The Clouds of Sils Maria,” Stewart is again playing the personal assistant to a powerful woman. But while the core of “Sils Maria” was the give-and-take between her and Juliette Binoche (the self-absorbed actor who employs her), the boss in “Personal Shopper” is more a plot device than anything else. This movie is all about Stewart; thankfully, she’s such an intriguing actor, she can handle it.
