Boston Globe's misconception of the Immaculate Conception

Perhaps ironically, the Boston Globe, in an article on the movie "The Nativity Story" titled "Film focuses on bringing accuracy to biblical tale," fails to report...accurately.

Keeping in mind that "The Nativity Story" focuses on the birth of Jesus, we read:

Stretched into something between fairy tale and religious quest, the film humanizes a bare-bones premise -- the Immaculate Conception -- by asking, "What did Mary and Joseph go through?"

This is called an example of a bare-bones mistake.
