We started watching Snowpiercer on HBO. Based on the movie, which was just OK at best. Stars Jennifer Connelly, who is way too thin, looks older than she is, and is no longer the best looking woman in Hollywood. She's good though. If you saw the movie, the premise is the same. Global warming caused humans to try to cool things down, and we screwed up and ushered in a new ice age. Oops. Some eclectic genius billionaire named Wilton created a perpetual motion train that goes around the world endlessly. It's 1001 cars long, with 3 official classes and "tailies" who stormed the train and boarded without tickets as it was set to go. Aside from those on the train, Earth is lifeless.
Once you get past the basic question "a train, really?", it's a story of society, class, privilege, and personal drama within that society. In that sense, the show far exceeds the movie, which didn't have enough time to explore it. Is there a lot or irrational stupidity? Yes. At one time, I might think people didn't behave that way. But increasingly, we clearly do. It's not great, but it's not bad really. Best if binged or at least if you continue watching without long pauses in the story. There are some resemblances to The 100 (which I liked), and really the last humans being out on a space ship/ark isn't much different than on a train/ark.
