Published in 1984, Gibson describes a Blade Runner type world complete with a matrix that humans jack-in-to for a virtual experience. This is years before Matrix films were created and released. Gibson even developed his own realistic "techno" language years before on-line world took off.
The biggest difficulty I had is Gibson's extensive use of this language. It adds to the story to make it more real, but slows the read and makes it at times hard to understand.
After hearing about this book for years, I finally had a chance to read it - and was a bit disappointed. While I will always appreciate this novel as the one that kicked off a whole new era of science fiction, there have been so many variations on this theme that Neuromancer's plot itself now comes across as a little plain.
I also had a little bit of trouble swallowing some of the plot points and character interactions - I spent a lot of time thinking "Well, I'm sure XYZ happened for a reason, but I wish I knew what that reason was."
I kept trying very hard to like this novel, being that it's been to sci-fi what Lord of the Rings was to fantasy, but it just seemed like a lot of work getting through the plot to finish a story I've heard retold a thousand times since it was written.
