In Lynne Ramsay’s “Die, My Love,” Jennifer Lawrence and Robert Pattinson play a married couple with a newborn who move into an old country house. In Ramsay’s messy and moving marital psychodrama, Lawrence plays an increasingly unhinged young mother named Grace whose postpartum depression reaches darkly hallucinatory extremes.

J. Law’s mesmerizing performance in “Die, My Love” is so good, expect her to show up on that Oscar stage again.
