Dear Zachary: A Letter to a Son About His Father

Maybe the most haunting documentary I’ve seen.

This true-crime saga, which helped bring changes to Canadian law, is comparable to having an open wound poked for 93 minutes.

It’s emotionally-lacerating, and, admittedly hard to watch at times, but the love for its fallen protagonists, which comes through in every frame, helps balance things.

Filmmaker Kurt Kuenne set out to make a film just for family and friends, a cinematic scrapbook which would capture childhood friend Andrew Bagby in happier times before his murder.

Instead it grew into something with far more widespread impact, and remains an enduring masterpiece of the genre.
