You can call this movie "TrainWorld". Or maybe "bugs on a train". Completely cheeseball, totally ridic - yeah, all of humanity is somehow stuck ON A TRAIN. And unexpectedly! Like, it can't stop. Maybe its really "Speed 3". Slow down and it blows up. Somehow 17 years have passed and we're all fed, on a train that can't stop. Brilliant and painful! Oh and there's a "caste" system where poor people are in the back, with "Mad Max" style grimey clothes. Embarassed just watching it.
Anyone rating this high, I think they just want to sound intelligent, or something. Like less is more, abstract means brilliance, etc. Because it tries to mimic what our real world is like (unfair, divided, casted).
