Yeah, I think people are more hung up today on "canon" and "continuity" than they used to be. I recently rewatched the old Universal "Mummy" movies which seemed to have a rather more laissez-faire attitude towards continuity. Decades passed between the films ("twenty years ago, your father uncovered an Egyptian tomb") and yet it always seemed to be the 1940s, the names of gods and temples changed, and, at one point, a New England town is transposed to Louisiana with no explanation!
I'm not sure anybody cared or noticed . . .
