Eh, it was Pullman's attempt to do the Anti-Narnia so the atheist overtones were the point. The first book was entertaining but the second and third ones went completely off the rails and ruined what could have been a good series. Lewis did the same, ironically, with his series' last two.The "His Dark Materials" (As in the Golden Compass) series is good. It isn't one of the new breed of YA novels but it shares all of the hallmarks of what a YA novel SHOULD be. There are some irritating atheist overtones in some of it (we get it, you don't like god) but overall it is a very well realized universe. Great series of novels for any teenager.
The film was shit but don't let that put you off.
So I suppose Pullman DID create the anti-Narnia.
