see, the problem is "evil".
i successfully watched the exorcist from the demon's perspective. granted, it helped pull me through a viewing at 2 am, alone, in a rural house, in the middle of a blizzard, but it kind of holds up to scrutiny.
and while it's methods were unorthodox, it was everyone else who was kind of freaking out. i think he would have given the little girl back, too, if some chump into demons came along.
if you write this book, please devote a chapter to the exorcist and how evil is way more nebulous than even the catholics thought?
