It'd be so much better if he were somehow able to actually show the people the reason for his "revenge" -- like planting his memories of what they did into them.
To be real, what he's doing to them would make very little sense from their perspective. Revenge is much more potent, and terrifying, when the target of it has a full grasp of what they did to deserve it; they'll know what they're really in for because of their actions.
This is all silly as hell anyway, so it doesn't really matter, I guess.
@Miros - I personally don't really care how they choose to adapt it, but I'm really looking forward to how entertaining the shitstorm following it will be. I can already imagine that one Australian politician (I think he's a politician at least) using this series as an example of the potential "corruption" of youth to argue for more censorship and bans.
