well..
From a technical/artistic point of view this flash is pretty good.
I don't get the story though. Following the analogy, the people only had to get off the track, instead they built a friggin wall so the train could crash and they had a good laugh.... while the train was crashing.
The message I'm getting here is, not only do we have to evade the "evil", we have to crush it. I prefer peaceful messages, because in the end I don't sympathize with the people. It's either the train or the people and obviously both have no problems in destroying each other.
