Though clearly an adoring tribute, Love, Antosha allows its subject a sort of complicated humanity that expands our understanding of him.

It serves as both a celebration of Yelchin's life and a tribute to his parents, particularly his mother. That infuses the film with a warmth and compassion that keeps it from feeling like a funeral-service memorial.

Mostly, the Antosha of "Love, Antosha" seems like a good kid: someone whose life -- and tragic death -- should inspire us to spend our brief time here as wisely and as well as he did.

One of the most heart-shattering documentaries ever made. But it’s also thought-provoking and inspiring. The world needs more people as kindhearted, authentic, and thoughtful as Anton.
