Good Night, Oppy is the story of Opportunity and Spirit, the twin rovers we sent to Mars more than 40 years ago.
They didn't live long enough to see if they'd ever find evidence of life, but they did live long enough to tell the story of humanity's "capacity for achingly beautiful love," writes Christy Lemire at RogerEbert.com.
"There's something to be said for the way our desire to find out if we're alone in the universe expresses humanity's capacity for achingly beautiful love," she writes.
"I went through a box of tissues while watching this movie," she adds.
"It's a heartwarming story and nigh impossible to avoid falling in love with the robots."
The rovers " embody humanity's desire to create and to love in the face of adversity; the scientists nickname Opportunity as if it's a ruly child," writes Lemire.
"The narration from NASA employees about the rovers is akin to a parent talking about their children," she writes.
"Grief is inherently intertwined with human life, if only because humans have the capacity to love so fiercely and deeply."
