I always thought the 2013 movie was too short, so after watching the movie i found myself reading the French graphic novel Le Transperceneige, later re-titled Snowpiercer 1: The Escape, created by Jacques Lob and Jean-Marc Rochette, and published in 1982.
In my enthusiasm, I also read the subsequent sequels, The Explorers and The Terminus.
Then years later i come across this Snowpiercer TV series and right from the start i am into it. The first 2 seasons follow the first book loosely with some additions and omissions.
The show starts strong, especially in the first two seasons, with great world-building and solid storylines. However, by Season 4, it slows down, and some parts feel stretched out. Jennifer Connelly and Sean Bean keep things interesting though, with Connelly adding real depth to her character, even when she disappears from the story at times.
Daveed Diggs doesn't quite fit the role of such a major character; there are several moments where his acting feels awkward and out of place.
Overall its a good and entertaining show, better then the movie but worse then the graphic novel series.
