Snowpiercer (2020)

Seven years after an attempt to cool the planet froze it solid, the last of humanity circles the globe on a train 1,001 carriages long, with the rich at the front and stowaways crammed into the Tail. It is louder and soapier than Silo, its first season takes a while to find its nerve, and its four seasons reach an ending built to serve as one. What makes it worth the ride for a Silo fan is Andre Layton, a Tail passenger hauled forward because he was a homicide detective before the freeze and there has been a murder. The case becomes his licence to walk through every class of the train, the way the sheriff's badge sends Juliette up and down the silo's stairs.
