True and good point, there is a lot more governed by religion and mysticism in their world than ours. I concede the point.
I'll admit that when I first read the books, it wasn't until the second book that the story moved towards magic (except Daenarys's dragons) and I wasn't happy with it. I was hoping for a pure kings and connivers story (which we got) not so much a wizards and witches theme. On film though, the story is much richer and fuller with the magic and fantasy elements.
