There are totally two fandoms in the Narnia fandom. With me I noticed that on ff.net they go by canon and can be pretty elitist when it comes to the movies. Anything different from the book, even if they're expanding on a certain scene, RUINS IT FOREVER. (I for one loved how in the first movie they expanded on the air-raids.)
The fandom on livejournal is open to pretty much everything and brought slash and incest into the story, pretty much dubbing it a fandom like every other (it's official now xD).

With me I don't know which side I'm on. I'm not very happy with some of the changes they're doing on VDT and on PC, but it doesn't make me hate them. And I adored the first movie!


So yeah, I can see your problem has more to do with fanfiction, but once I saw the topic I was like "I KNOOOW". =P
