Odd choice. Why make a film that has a built in audience (Catholics) but then make it in a way that will make the target audience not want to see it???
Evil can't stand to see holiness and therefore tries to destroy it.
It's audience is not Catholics, but ex-Catholics. Their infidelity needs reinforcement.
"Why make a film..."
If one has a battle agenda to demoralize and scandalize in a war on deconstructing western civilization, then this would be a nice Gramscian attack. A few years back there was a great FR thread titled " Deconstructing the Western Mind: Gramscian-Marxist Subversion of Faith and Education" and here is the old link. If it doesn't work try to google the title.
