The summary you mentioned may be the one here (http://wrongquestions.blogspot.com/2005/07/his-dark-materials-by-philip-pullman.html). Hilarious. I, too, was rather boggled by the lack-of-love charge. I, like you, assume that this is a product of the fact that Pullman does not actually understand love in any of its forms, whereas Lewis understood it in several, if not all, of its forms.
