Just thought of another, and for an actual book this time:

I forget who wrote it, and a quick Google search didn't turn it up, but there is a paint-peeling rant about the Jean M. Aul books, particularly the way "Valley of the Horses," which devolved into laughably unrealistic soft-core cave porn.

You might be able to find it via Godawful FanFic, which I'm not going to search now because I'm at work.
