Bold, but aimless....
Although this flash had a strong stylistic element, and was masterfully done, it's hard to understand where the focus lies. There are times where the animation become too uncomfortable, and I refer to something other than the violence. It seems as though, through certains points, that you are almost empathetic for the killers...almost as if the killing of innocents was somehow just and right. The whole animation seemed to eminate from the point of view of Harris and Klebold, and focused mainly on how they felt bullied and cast out, without so much as a nod to the fact that 70% of all school pupils feel that way. There was no explanation, or even speculation, on your part as to why they did this, further than the usual "we were bullied" view.
As I said, a masterful flash, but slightly disturbing in it's sympathy towards the murderers, and not the victims, with no insight into social or personal matters.
You've proven yourself adept at tackling difficult issues intelligently, but try to be more objective in your stance.
