Locke and Key is a difficult beast to describe. It’s fantasy, with elements like magic and creepy mansions, but set in the modern world, with 'real' people. It’s horror, with murderous students and sinister villains, but it’s not like a Hack/Slash or 30 Days of Night-type horror. In fact, it's a perfect blend of both genres. It’s The Chronicles of Narnia meets H.P. Lovecraft. It’s Dark Fantasy done right. OK, so that wasn’t so difficult after all…
