I must be really missing something with Snowpiercer. I watched it a few days ago and didn't enjoy it almost at all. The social commentary lacked any nuance, there were multiple pace breaking scenes of exposition dump, the tone and plot events were all over the place, and there some things that maybe got explained in the graphic novel but unless I missed it had no explanation in the movie. It had it's moments but was overall a resounding meh, and outside online forums I know nobody who enjoyed it.
