NOTE: By mentioning a major brand, I may be violating #BrandZero; however, I need to mention it to illustrate a larger point. I’ve give a fuller explanation tomorrow.
Nothing occupies a fandom’s attention more than what is and is not canon. The entire concept of “canonicity” arises naturally from reading a series of connected stories — things have to be consistent across all of them to replicate the experience of the first. If the story goes on for a long time, you will take joy in not only what doesn’t change, but what does change and has an impact on the story’s world.
However, not all canons are so tight. Sometimes, you get a loose canon that keeps some elements consistent while changing others without regard for what came before.
