It is tribute, even if what it is ends up being "Here be dragons" about the series, and since I still see people reading the series, I want them to go in with some knowledge of what is happening.

I also think that for some part of fannish history (and now), the people having a reaction that all critique is bad sometimes includes the authors of the work themselves. So there's also a certain amount of spite involved in creating out, since the author was very protective of her series in life.
