I am a sci-fi nerd and I also found Neuromancer incredibly boring,I'm curious... if you're willing to say, when did you first read Neuromancer? And had you read a lot of other cyberpunk themed media beforehand?
but that's probably because it introduced so many concepts that others went on to refine.
Yeah, if you'd already been exposed to a lot of the core ideas / themes from other more contemporary works, I can see how that might take away a bit from the Neuromancer experience.
To give a counterpoint... I first read Neuromancer about 1993 / 1994 or somewhere in that range. And I believe it was the first cyberpunk novel I'd read. I think maybe the only other media from the cyberpunk genre that I'd been exposed to then was the "Max Headroom" tv show. Anyway... Neuromancer absolutely blew my mind and I was instantly hooked. To this day it's one of my favorite novels, and I've re-read it several subsequent times. And will almost certainly read it again (and again...) I can't get enough of it.
Of course it's hard to say exactly why our respective reactions to it are so different. There are a lot of variables. But I think your notion from above has a lot of merit to it. If one experiences a derivative (or many derivatives) of something before the original, does the original them come to feel like a cheap copy?
I've had that experience with cover versions of songs before. That is, times when I heard and loved a cover, and then only later heard the original. And in many (maybe all) of those cases, I still preferred the cover over the original.
