'Dead to Me' creator on grief, friendship, and improv

In the Netflix dramedy series ‘Dead to Me,’ Christina Applegate plays new widow Jen, in shock after a hit and run killed her husband while he was out for a late-night jog. Grieving and angry, she reluctantly goes to a grief support group, where she meets Judy, played by Linda Cardellini. She tells Jen and the others in the group that she’s just lost her fiance. And they believe her...at first.
