I doubt that you’ll find much to object to in the first film. From what I’ve read, it’s in the third installment of the trilogy that we learn that God is a weak fraud and that Christianity is a scam created to keep young people from enjoying sex.
It’ll be interesting to see how they handle that in the third installment, if the series gets that far.
I’m pretty sure we won’t find anything to object to, unless it’s just a crummy movie. The only movie I can recall recently that really was offensive, was ‘The Road To Terabithia’.
But as fiction, how does it really matter?
