Josh Peterson’s review published on Letterboxd:
It's apparent that Sarah Polley commanded and pushed her cast and crew to do their best, and this confidence shines through the heartstopping performances and how the camerawork establishes every group dynamic. Seriously, the way she makes the most out of a single central location is commendable and just shy of the very best (12 Angry Men, Mass, Scenes from a Marriage, etc.). It helps that the writing is consistently mesmerizing too!
It's a little overedited with its flashbacks and the music is overbearing in a couple scenes, but overall is captivating and piercing and the emotional power reigns far supreme. My second watch thoroughly moved me just the same... maybe even a little more after a few months of reflection.
