The Snow Piercer premise is about as useless as any “hey, let’s put people in a bottle episode” premise …
it’s an idealized Skinner box style trolley problem fuck fest … with many deos ex machina escape ramps …
it has a decent character assemblage and overall story …
it was done differently in 2014 …
Also: wouldn’t people had thought “hey, fuck, life has hung on around geothermal vents since FUCKING FOREVER …” …
