I have always liked backstory sections of novels/series. I also like history in general, so my enjoyment came from the telling of Rolands backstory and finding out what shaped him into the character that he became. It didn't have anything to do with the fact that it was a love story. But, being a love story didn't detract from it.
Also, I believe that in our polls at least, SoS came up last, and W & G came out on top. So, it seems that there are a few others who have the same tastes, though everyone is justified in their preferences.
