Just canvassing opinions, really.
The subject of my interest is a novel that has long been in the public domain. It has been very famously adapted, but the novel itself remains relatively obscure.
I begin to research the period about which it was written, and from this a new project has emerged - a sort of companion novel. I shared my idea with a friend, who remarked (rather sniffily) ? ?You mean like fanfiction??
Admittedly, her reaction pissed me off slightly, but it did get me thinking.
What about, say, Wide Sargasso Sea or Death Comes to Pemberley.
When does fanfiction become ? legitimate ? for want of a better word?
