Fans know there is a difference but I don't get irked by them lumping it together as long as it gets recognized. I read either as the mood takes me. I'll read it in secular fiction, I'll read it in Christian fiction. Also, sometimes, the lines between fantasy and science fiction blur depending on the author. Not all of SF is space ships and star battles (in fact, military SF is one of those things I avoid reading...no interest), and outright war stories with fantasy elements? Same thing. I don't like them much. But author who did the Darkover series tended to blend elements of both depending on her story, same for Anne McCaffery. Generally, I'm happy just to see a good selection of both at the library or the bookstores. It's usually easy to tell which is which. At the library I am at right now, they have put stickers on the spines of the books, one for fantasy titles and one for SF.
Hmmm...I remember the Magazine of Fantasy and Science Fiction
Agreed on some of those authors above, Moorcock, Burroughs (loved the both as a kid and young adult).
I also tend to agree that fantasy has become predictable and generally boring. I don't read it nearly as much as I used to. There is really only so much a writer can do with fantasy plots, Heroic fantasy, dragons, magic, battles, evil gods, despots and tyrannical rulers. Yeah, some can come up with new stuff, things with a bit of twist on the old stories, but most of it is same old-same old. This does NOT mean that some fantasy writers are not interesting. Some are quite capable of crafting a wonderful story, but there seem to be fewer and fewer these days who write in ways that capture my attention.
One other pet peeve about fantasy novels is that they have gotten ridiculously LONG! Sheesh. 600 to 700 pages is ridiculous. I realize they want to craft interesting worlds and cultures and governments and many do succeed at it. But they lose me if the plot is just the usual fare. I remember the 'good old days' of Burroughs, Lin Carter, L. Sprague De Camp, norton, Moorcock and Lieber etc. who could write a 200-250 page book (which I could often read in 2 nights of easy reading) and they were more than capable of creating interesting characters and plots, as well as 'world building' within those 'limited' number of pages. I long for the days when I could pick up a book and be done with it in a matter of a few days even when pulled in many other directions by life's general obligations.
