Yes, I admit, I have occasionally thought why are these people all '*shakes fist* that damn magic, solving everyone's problems again!' I even understand that if it's one of those universes where only certain people can do it then there might be a frustration and mistrust. But just dismissing all of it as 'meh, magic again' makes me look at them funny too. But in the Discworld novels that kind of works for me.

No, I know exactly what you mean, I love reading about antagonistic friendships and partnerships. But some people in books just aren't interesting enough to put the work in, or maybe it's not that they're not interesting so much as they don't feel believable in themselves and the way they relate to others?
