Science Fantasy is a weird category. I mean you take a futuristic setting and then treat is as Fantasy with minimal work on the science side. I would argue that most of Star Wars fits that bill.
However, why put Ilium by Dan Simmons as Science Fantasy? As far as I recall, the science was pretty well grounded.
Oooh, the Blue Core Trilogy. So much potential on that one. With some tightening of plot and more character depth it could very well have been Great instead of merely Good.
