Different fans have different sensibilities when it comes to how much weight they place on canon.
Some seem to get off on trying to make it all fit together, as if it's historical documents.
To me, canon comes first, but not all canon gets elevated to my special place of things that I enjoy and revisit. I certainly don't subscribe to the notion that canon fits together into a consistent picture; it's fraught with production mistakes, contradictions, false starts, revisions, and things that shouldn't have been included in the first place.
There are whole episodes that I could comfortably go the rest of my life without ever seeing or even thinking about again (only slight exaggeration for effect on the latter part, there). I'm looking at you, Miri
and Turnabout Intruder.
