It's a chilling film for sure, yet so very very deeply warm and human but with no cheap pathos nor any sentimentality whatsoever. "Raw" is a good way of describing it, no lose ends, no extra parts - just human. You can feel that Spencer Tracy really poured his soul into the role... the ending doesn't fail to give me a shiver every time I watch it. And the theme is... strikingly fresh for our times (or any times...) So glad new people are still discovering it!
