Gibson is incredible at conjuring up his environments. On the other hand, his prose is also second to none, usually.

All that said, just imagine how fantastic his novels could be with better plotting! He's not terrible at characters, it's the plot that ultimately disappoint. I think his imagination peaked with Neuromancer, unfortunately; his later novels didn't bring much new to the table beyond what he's laid out in that book, and I find his later obsession with art (like the locational VR art in the Blue Ant trilogy) and video games tiresome. His newest one didn't click for me at all.

Lost, ugh. Such a promising start completely wasted by lack of planning.
