Ugh, they do do that, don't they. I've heard of that from God Awful Movies when they visit Christian movies in theatre, places are ghost towns sometimes (and those movies sometimes end with the maker begging people to buy extra tickets).
Also this movie might be a contender, if it's enough of a flat out lie of a movie, lol
Back when I was forced to go to church, there used to be drives where we would take a second offering to buy up tickets for Christian movies in the theaters and "give them to people who needed to see the movie." I went to one once. I was the only one there. Where did that money go, huh?
I think you know, haha. The podcast I mentioned also sometimes has guests who had to sit through those things a kids, so that tracks. It's probably funny/sad to revisit some of those films.
The only nostalgia I have for anything Christian was for a Legend of Zelda clone that I played as a kid called Spiritual Warfare. I kinda want to go back and play it, but I have so many other, better things to do.
