When I read the Fifty Shades trilogy, I came away with a slightly different opinion of it than he did - though that difference was mostly in the nuances and degrees.
As a work of fiction, I found it intrinsically without value. However, it has extrinsic value as a statement on our (American) popular culture. I don't believe that's a particularly kind statement, by the way. I can't speak for the trilogy's reception in other countries.
That said, I actually enjoyed the read. It's superficial, but enjoyable until you look at it in an analytic light - even if some of that enjoyment comes at the author's expense, or is rooted in a sardonic view of the culture which produced and consumes this drivel.
A bit later in the conversation, with more information gathered, Archer had this to add:
Did I mention that Archer can be quite scathing when provoked?
