There is some truth to this:
"This is what British sci-fi author M. John Harrison called "the clomping foot of nerdism" and, unfortunately for all of us, it has taken over. In
an essay which caused a storm in sci-fi's teacup back in 2007, Harrison criticised the urge, felt by both authors and fans, to exhaustively catalogue every detail of an unreal world as if it were a real place rather than a literary device. Often, nerd desire for this kind of encyclopaedic knowledge outstrips the author's ability to provide it. William Gibson, the author of Neuromancer,
recalls a visit from two men who wanted to turn it into a Dungeons and Dragons style roleplaying game"
It is a problem with Star Wars as well. Who gives a crap about what yoda used to do back in the old days? Ah, I see he refers to Star wars later in the article.
" What's more, the very activity of canon formation is what nerds most enjoy: obsessively mastering a set of authorised texts, declaring their group allegiance through their memory of its most obscure passages, and then lawyering each other furiously wherever the authors leave gaps. We would all be so much better off had fantasy authors followed the example of elderly Tolkien, or even Borges himself, and just written fictional encyclopaedias"
That being said, canon, in the form of Star Wars canon, does have value. It leaves some entertaining things unsaid and leaves some mysterious features of that universe. Going back and filling that in was never the right decision.I wish I were more articulate about that, because I'm a fan of canon both for LOTR and Star Wars.
I believe the article may be implying that The Hobbit is better written than LOTR. With that I agree.
