Why does the fantasy genre have such a bad reputation?

[Albertosaurus Rex]

Just noticed this review over at SF Site: Earth Girls Are Deadly. It's a review of a self-published book and... not a very good one, by the sound of it. (Unless tentacle rape is your thing.) Seriously, why give attention to it at all? It only serves to drag down all of SFF.

(I always wonder why SF Site does self-published books anyway. Although we all know the stories of brilliant books that were rejected by publishers, it's usually a bad sign if you can't get your book past an editor. While there are always diamonds in the rough, I question this practice of SF Site.)

EDIT: Alright, I might be wrong about this book being self-published... sort of. Tuppshar press has only a LiveJournal as website and appears to be a publisher devoted to publishing porn novels with cheap-looking 3D CG covers. It's not quite self-publishing, but it looks pretty damn close.
