I'm having a hard time with this one. Not the faintest hint of an idea. Sure, I may serve my meals pretty late, but I do have at least a few ideas cooking.
Anyway, considering what I've read and watched, the monster remains inhuman and incomprehensible mostly by remaining shrouded in mystery exactly because we don't have their POV showing us emotions/motivations that could make us understand what makes them tick.
It's like instead of writing a story from a random professor, I'm trying to put Cthulhu's thoughts and perspectives on the page, when it's exactly by not doing it that makes him/her/it so alien...
