What do you guys think about The Chronicles of Narnia?

So I finally got around to watching the most recent movie. I don't
know what it is about them, but I just really really like these
movies. I think it's just the fantasy and the scenes. The characters I
have grown to love. I like how they have a sort of Christian theme.
But it's not really centering around it though, you know? I also enjoy
the soundtrack. I never got around to reading the books, however I do
own all of them...

I was just wondering what all of you thought about the series; both
the books and movies.

Thanks for your answers in advance. Also, if any of you could tell me
some book and/or movie series similar to TCoN I would appreciate it
very much :)
