To those who don't read genre fiction, the difference between fantasy and science fiction (SF) probably seems pretty small, like the difference between techno music and house. But to fans of these generes, the differences are usually really clear. One common critique is that fantasy fiction tends to have less variety than SF.
The common complaint is that while SF is endlessly creative, showing us wild worlds we've never imagined, fantasy tends to rip of The Lord of the Rings most of the time. Particularly, people pretty sick of elves.
Certainly, if one read the "sword and sorcery" subgenre of fantasy, it might look this way. (Not all fantasy is sword and sorcery-- you can check out "urban fantasy" too.) But here's the thing: people love elves and dwarfs and dragons. The other way to look at it is that SF has failed to come up with any species prototypes that people love enough to want to read about again and again-- fantasy and horror has. Elves are like vampires and werewolves and zombies-- people can't get enough of them. Why don't we have lots of novels about the Buggers from Ender's Game? Or at least cheap rip-offs of them? If buggers are not human enough, how about Star Trek's Klingons?
Interestingly, not every Tolkien race took off either: not every fantasy world has ents or hobbits. On that topic, many of the races that we describe as Tolkienesque he borrowed from much older mythology: dwarfs, elves, dragons, goblins. Orcs have been moderately successful, but they're not ubiquitous like elves are. It suggests that the successful fantasy races are successful because they are inherited from a time-worn tradition of compelling archetypes: the faerie, the dragon, the hairy beast in the wilderness, the elf, the demon. A tradition much older than Tolkien.
