Is Coraline inspired by Silent Hill?
Both are set in foggy settings and is about a parallel universe called the Other World
Both parallel universes are controlled by supernatural female demonic god-like entities who create demonic creatures that are representatives of the people in the real world that the protagonist lives in
Both parallel universes unravel/transition whenever it reverts to its true form
Both protagonists of Coraline and Silent Hill are provided clues in the climax in their respective Other Worlds
Both protagonists live in foggy settings in the real world
Both OSTs sound eerily familiar in a creepy and "atmospheric" kinda way.
And I'd also like to add that Harry Mason and his daughter Cheryl (protagonists of Silent Hill) stayed in Oregon after the events of the first game (I'm not sure please correct me), the same state where the events of Coraline took place. Not really part of the theory but its interesting how coincidental this is.
