My Dead Friend Zoe,” starring Natalie Morales and Sonequa Martin-Green, confronts a dark reality of post-combat struggle with as much humor and playfulness as it does trauma and sorrow.

The scenes Martin-Green shares with Harris, of the "suck-it-up" school of processing grief, and Morales, irreverent and irresistible as Zoe's livewire ghost, spark with an energy that also underlines how easy it is to leave the mental challenges of returning soldiers unaddressed.
