My wacky ending interpretation
So the general conclusion on these boards is that they end up in the belly of the beast. And that's also my interpretation of the ending. But then I thought some more and maybe it's more literal than we think. Maybe they ended up inside the bowels of the mysterious dog that wandered the premises. I know it's absurd, and I've had a couple of whiskeys, but there were actually some clues troughout the movie that got me thinking :) When they first visit the church, upon seeing the dog (ripping something apart), Gray says the following: "That's nature for you, Deacon. Big stuff eating little stuff". Then he references the Hound of the Baskervilles later on, when the dog suddenly appears after they hear the scratching noises in the walls. Finally there's Deacon stepping in dog poop on his way to the church, as sort of an omen to where they'll end up. Oh yeah, and "dog" spells "god" backwards, meaning what they encountered and ended up in was the opposite of god :)
There you go, dogfood for thought ;) That rottweiler was Chekhov's gun. Goodnight!
