Oh, I freaking LOVED the ideas in this - and I'm glad that it had an ending; I kept watching the bar scroll down and thought, if this cuts out mid-sentence and I don't figure out what happened I am going to do VIOLENCE. But mostly, I keep flailing because, hello: hunters going back to the dawn of time; Castiel being a kind of heavenly ambassador, then suddenly unable to do anything but watch; a... whatever the hell that thing was, trying to be a new, more satisfactory kind of God with a shitty themepark Heaven - this is one big bundle of brilliant ideas. I hope that, one day, you finish this to your own satisfaction - but as WIPs go, it's pretty damn satisfying.
