A little background on myself for some perspective: I'm a middle-aged Roman Catholic single father of three, who attends church regularly (a few times per month) and generally leans a bit toward the right. I'm certainly not fanatical, but am somewhat spiritual. And just to clear up any misconception, Catholicism is, in fact, a Christian religion.
My teenaged son and I watched this movie together, and I don't know his impression specifically, but he did watch the entire movie, which is generally an indication he likes it. I enjoyed the movie as well, and did not find it to be in the least bit mean-spirited or anti-Christian. The main character never denounces God, but merely changes her perspective to one that's a bit less fanatical. The fact is, some people do go to extremes in their religious zeal (anyone familiar with 9/11), and simply depicting such a character in a movie hardly makes it anti-Christian. I think this movie represented a very accurate cross-section of religious attitudes in our society. If you are a religious zealot, or anti-religion zealot, you probably won't enjoy it because it doesn't lean in favor of either extreme. All others may find it worth the price of the rental.
And just to address some of the other reviewer comments - not wanting to regulate morality does not make one immoral, and if you think your sexual preference is a choice, think back to the time you CHOSE to be heterosexual.
Come now, you surely must remember a significant decision like that (and no, I'm not gay).
