SNowpiercerFirst adapted from a French graphic novel by “Parasite” director Bong Joon Ho for his 2014 film, the new TV series of “Snowpiercer” (TNT, 9 p.m.) has the same elaborate dystopia set up: a 1,000 car train circling a frozen, unlivable earth with the wealthy in luxury cars up front, and the poor packed together and barely surviving in the end. But here, the class struggle on wheels gets that TV treatment that requires a detective solving a murder. Still, it’s kind of fascinating; Daveed Diggs has his best TV role yet as the former cop straddling two worlds and Jennifer Connelly portrays a train official who needs his help.
