PS: I Love You (2007)

Holly (Hilary Swank) loses her husband before she is 30 to a brain tumor and enters a period of "over-the-top" grieving.  Then letters start arriving that her husband has arranged before his exit.  So the plot is unbelievable, but if you treat it as something like a fairy story and go for the ride, the movie is OK (not great).  The photo shows Holly and her mother (Kathy Bates) walking in Central Park.
