The James Frey one is the worse!
I'm a newbie to AW, and I hope I don't get off on the wrong foot here by noting that the boundary between egregiously bad sex writing and pretty damn good writing seems pretty porous to me. Some of the quotes in The Guardian article are truly execrable. Others are on the side of "Damn, you almost had it there, but you just didn't get it quite right." The point being, there are some good concepts and good writing in those passages. It's not all "vagina-rachet" awful.
