If it's true to the theme of "Flags of Our Fathers", as you depict it, it's movie about a pregnant teen, unable to get an abortion in Nazareth, who tricks an older man into believing he's the father, so he takes her to Bethlehem where there are shepherds who will arrange for doctors from the East to perform the deed.
I get your point, but trust me, the "Nativity" movie may well be THE sleeper of the year. It has that "Passion of the Christ" magic, with a less grueling story line.
