An interesting article, most certainly. I suppose the immediate response is the critic sphere is heavily self selected for people who really like books / movies / comics / etc. So what to most normal people would seem like

For point of reference, shotgun slugs can be stopped by modern armor. It still cracks people's ribs through sheer impulse. A 50 BMG has 5 times the kinetic energy and 3 times the momentum of that. It's simply not enough to stop th
