So I think that even if there were fairly big issues with the story, it would serve as a starting-point for discussion. "What do you think the bible says about this? Shall we look at what Jesus says about these things?"

I've heard praise about it from Christian friends of mine, they tend towards the Evangelical side of things rather than the liberal side, and it may very well be that they're happy about a positive Christian portrayal, rather than the caricature that we're accustomed to seeing.
