Snowpiercer

... get plenty of zzz's before you sit there in the dark wondering how so much mayhem can happen on such a little train, the little train that could, or is that engine? Murder on the Orient Express this ain't. The plot was plodding and boring. I kept dozing off, no less than four times so the story sustained a rather chaotic line which, as it turnes out, may have been the director's intent. Lol! If this was supposed to be a metaphor for planet Earth, I found the comparison simplistic and naive even if I extended the ultimate in suspending reality.
