Easily done? I'm sorry but history doesn't support your claim regarding the ease. However, that's not to say it cannot be done. I've always been of the belief that too many people like to complain about movies and TV, and not enough willing to stick their necks out and actually try and make the kinds of movies and tv shows they'd like to see.
The problem is, and this is a cross ideology problem, if you try to hard to force your particular political/Sociological bent into your script, the movie/tv show looks too forced, and ends up flopping. Also, Conservative/Christian programming does have to compete with other movies/TV programs, both in themes, as well as visually. The production values have to be at least as high as the level of competition. Too many times that just hasn't been the case. Let's face it, Left Behind failed because it just looked dated by the visual standards of today's current movie releases. You cannot expect to compete with inferior product, regardless of how much you believe in the storylines.
I'm glad to see someone has finally gotten the stones enough to pick up the challenge I regularly tossed at folks who complain "If you don't like it, go do it yourself, and show them how you think it ought to be done"
BTW, if you want a great example of excellent production values, good performance levels, and the audience approval that backs up what I'm suggesting here, look at "Touched By An Angel". It proves a very old Theory of mind, People aren't opposed to watching shows with God in the story, as long as the Producers aren't reaching out from the TV set and bashing them over the heads with their Bibles.
