I think part of what's going on in Pullman's trilogy is that he's more interested in making certain philosophical points about independence of mind and standing up to authority, and less interested in making the characters into people you'd want to actually know in real life. Also, notwithstanding the fact that Pullman has claimed, in at least one interview that I read, to be interested in telling good stories above all else, I don't see the storyline as being the element upon which he concentrates the most in the "Dark Materials" trilogy.
