Do the spirits of the recently departed hang around to watch over those they left behind? It's a question that Oliver Assayas pointedly refuses to answer in his supernatural mystery "Personal Shopper," leaving the viewer to draw their own conclusions by the intriguingly ambiguous ending. While it's a film that will madden people who like everything spelled out for them, it provides plenty to chew on for those who like to puzzle things out for themselves. Even so, the conclusions you arrive at will likely be influenced by your own beliefs or unanswered questions about the supernatural and the afterlife.

One thing we can say for certain is that the film provides an excellent showcase for Kristen Stewart. It has been fascinating to watch how she and her "Twilight" co-star Robert Pattinson have developed since playing their breakthrough roles in the dreary five-part adaptation of Stephanie Meyer's sappy teen vampire saga.
