Dated?

I didn't read the book, so I'm not at all sure if that makes a difference ... but I think Dostoevsky's view of religion is childishly naïve. Now, I know that atheism was associated with nihilism and terrorism in the time he lived, and when this movie was made not believing in god was still interchangeable with being a communist but it bothers me that such an introspective writer could have such simple views on such a complicated subject. The religious people in the movie are wise and pure beyond belief (no pun intended), and anyone who has the slightest doubt is a murderer, a moron, guilt-ridden, or a coward, or some combination. This is just one-dimensional, lazy characterization, no? The "preachiness," as another commenter noted, doesn't bother me, it's that it's not even done in an interesting or subtle way that ruins everything. I can't help but think it makes the whole thing look dated and cheesy. If written today, I dread suspect this would probably be marketed as Christian fiction and be sold in the bookstore next to the Bible-quote-a-day desk calendar. Anyone have the same feelings?
