Filipe Coutinho’s review published on Letterboxd:
Sound of Metal is a powerful and deeply sensitive cinematic experience that manages to do two essential things: treat the subject matter with care, respect, and maturity; and create the feeling that the choices the protagonist makes are a product of a thinking, flawed, emotionally-driven human being, not just token-actions to service plot points. Whereas several films like this bank on the empathy generated by the premise to get away with conventional storylines, Darius and Abraham Marder use it merely as a stepping stone for a thoughtful exploration of what sound (and the lack there of) means to us, especially at a time when people are turning more and more into physical and spiritual practices to tune out the ‘noise’.
This is to say that Metal doesn’t pander and it also doesn’t exploit. There’s intention behind every sequence, art in every frame. To watch it is to go through an experience, one that can fill the soul. If you give to it, if you open up to the world. Metal is a deeply humanist film. It understands the wide-spectrum of complexities and goes along for the mountains and the valleys. There’s no judgement, no moral vindication, no finger-pointing. It’s just people trying to live life with the cards they’ve been dealt, trying to adapt. It’s profoundly touching. And it’s a knockout.
