If you read it today, it seems trite, like Snow Crash. If you read Neuromancer in 1984, it was mind-blowing. Same thing with Snow Crash in 1992. These books were decades ahead of their time.
Neuromancer is more like PKDick, in that they are adult-themed books more about personal problems with sci-fi on the side, and it is actually part one of a number of book with the same character (e.g., Count Zero). That can be boring to someone expecting lots of "pew-pew-pew I hacked the mainframe". Snow Crash also didn't really age well in terms of dorkiness (cyberdogs breaking the sound barrier, nukes attached to a biker-thugs brain, gangs in cyberspace ?!?!?, etc.), but at the time we were all floored by the new concepts.
