Even as a Christian I find these sorts of movies insufferable. It's made to be the sort of thing "Christians" want to see, and while apparently that works for some, what gets me really compelled is the stuff I DON'T want to hear. I want tough analyses of the Bible that look at the plausibility of things, and the stories in the context of their time. I've read the works of people like John Spong, whose extremely historical and scholarly approach to the Bible shows that that Mary wasn't called a virgin until the later gospels and Joseph didn't exist until those same later gospels (because of Mary is a virgin you need some kind of a father figure to make sure Jesus isn't dismissed as a bastard, which is exactly how he is addressed in the early gospels), and that the prophecy from Isaiah which Matthew references to demonstrate that the messiah was predicted to come from a virgin was actually a Greek mistranslation which took the word Hebrew "almah" which is simply a young woman of childbearing years (marital status unspecified) and translated it as "parthenos" which does mean "virgin."
So yeah, after seeing some extremely hard to fight reasons for Mary to not have been a virgin, stuff like this comes off at best as rather soft. And at worst it's self-gratifying, self-righteous, and downright masturbatory. Certain types of Christians get off on this stuff the way housewives get off on 50 Shades. This stuff doesn't challenge or compel anybody looking for a challenge to their faith or a compelling reason to consider Christianity, it's a way for Christians who want to maintain their status quo and not think about new things to feel secure in their beliefs. By the end they're like "Yeah, porn's bad, and I knew that. Faith validated, Jesus points earned."
