I recently had an interesting discussion with some relatives that I thought could make for a really interesting discussion if opened up for a much broader audience. What I suggested is that I think that all of science fiction can be placed into one of two very broad, very general categories that, like the yin-yang of Taoist philosophy, are fundamentally very different and yet compliment each other very well - or at least needn't be utterly in opposition. I'll, for simplicity's sake, just call these two categories serious science fiction and adventure science fiction. Sure, the "Serious" type can be adventurous and the "Adventurous" type can have a serious aspect: but, in general, the one's the more intellectual type, the other's mostly just about fun.
So, Category A is science fiction that tries to be exactly that: fiction, but based on science. In other words, this sort tries to be true to scientific reality, at least such as it's understood at the time in which it's written. Into this heading I'd put Bradbury, Asimov, Arthur C. Clarke and the like.
Category B is more in the school of doesn't give a pile of rat-droppings whether or not it's true to scientific reality, it's just all about thrills, it's all about fun. Here's where I'd place your Flash Gordons, your Buck Rogers, all your space opera, all your pulps that portray Mars and Venus as being habitable, and the like.
Of course, there are some that are a little difficult to clearly place in one category or the other, like, say, Frank Herbert. On the one hand, his stuff definitely has some strong overtones of space opera (Medieval feudalism with Space Age technology), but, at the same time, it's definitely very deep and very cerebral.
Still, overall I think this is a workable system.
