That might be some of the difference then! I've always been an atheist, though educated in Christian schools, but it wasn't until my mid-teens that I actually understood that many people believed in God in a way that was different to the way I believed in books as I read them. I still don't really understand religious belief on an emotional level, though I wish I did. So to me, it wasn't a grand apocalyptic ending leading to a better place - it was a betrayal and a destruction, and a deliberate authorial decision to say that no, Narnia cannot exist in parallel to our world.
