The death of a parent, at almost any age, leaves a mark, but the effect it has on very young children is especially confounding. “Beautiful Something Left Behind” is a simple, elegant documentary about children coping with such heartbreaking loss, at a facility designed especially for them.

It’s a place called Good Grief, a large clapboard house in New Jersey (the film focuses on its Morristown location, one of two in the state). In a one-on-one session with an adult staff member, a child tries to give colors to his feelings. Blue and red, he says, are how he feels when he’s “sad and really mad.” The movie then shows a group-therapy session, with children from six to about 10 years old doing recovery-room-style sharing.

We like to think of children as being more emotionally candid and expressive than adults. Among the moments this picture, directed by Katrine Philp, shows us is how kids put on brave faces and try to deflect what they’re actually feeling. This is even more painful to witness than a child’s overt sadness. Also striking is how the children are made to understand the way some parents met their ends. You may shudder when one uses “bad medicine” to describe the cause of his father’s death.

Philp does not have any talking-head interviews with the staff of Good Grief; only the children address the camera directly. She structures the movie in a loose, satisfying seasons-of-the-year narrative.

It could be argued that the film needed a little more documentary-style explanation about how the facility works — how long children stay, the goals of the treatment, and so on. But ultimately, Philp can’t be blamed for stressing emotional engagement over exposition.
