In many sentences:
The world that Gibson creates in Neuromancer is by far the best aspect of the book. You don't even have to consider the time period it was written to appreciate it, just the entire scope of this futuristic, cyber punk universe with data thieves, modified humans, and rogue AI is great to read and think about.
With all that said, however, this wasn't a great book. For example, why does end it with an obtuse reference to things being the same now that Wintermute/Neuromancer has been merged and freed? Obviously it was important for Wintermute to orchestrate this, but it didn't actually do anything? I've been told that there is a sequel, but if it's true that the importance of the events for this book were saved for the next book, then that's even more annoying.
I also didn't enjoy how so much of the book (not just the ending) was deliberately obfuscated. Why does it have to be confusing about the Zion characters? And about Linda and her role in the story? Why does everything have to be generally ill-explained to the point of frustration? I enjoy when a book subtly reveals the nature of its fictional world, but only when those revelations are actually made. To me, it felt like Gibson wanted to make these subtle revelations, but was too lazy to do it and it ended up just being deliberately confusing.
I think this is a book worth reading if you enjoy science fiction and cyber punk in particular, but I wouldn't recommend it to most readers.
