As Cronenberg has observed: “Dead Ringers is conceptual science fiction, the concept being: ‘What if there could be identical twins?’ I’m suggesting that’s impossible. I can imagine a world in which they are only a concept, like mermaids.”
I was hesitating between a 4.5 and a 5, until last 5 minutes... this is called a classic sci-fi, not because how sophisticated the visual effect it has, but how humanity can be expressed in the form of robotics.
