The documentary This Much We Know is like an essay in motion, pursuing tangents and possibilities but always circling back to the initial impulse, the unanswered question. It ponders a painful subject—suicide—but as director Lily Frances Henderson pulls on different threads, she also considers the unknowable. Concepts that are hard to fathom, with odds so phenomenal, they seem unreal until they’re not—and how people deal with such uncertainty. Henderson lost a friend to suicide years earlier. This Much We Know is sparse on details about her friend’s life, but what triggered her death inspired this film, essentially a peek inside Henderson’s mind. She has no easy answers, but she’s thoughtful and considerate.
