Snowpiercer

More than seven years after Earth becomes a frozen wasteland, the last survivors live aboard a massive train circling the globe. As its passengers struggle with class divisions and scarce resources, a detective from the train’s poorest section is drawn into a dangerous investigation.

My take

You may enjoy this if you like dystopian survival stories, class conflict, and mystery-driven tension, but Not for you if unrealistic world-building, uneven acting, or comparisons with the 2013 film are dealbreakers.
