As a Catholic, I would watch bad films with a lot of big Christian overtones. I know my parents would automatically think a movie is good because it talks about Jesus.
Stuff like God's Not Dead, God's Not Dead 2... or other trash that tries to say something thought provoking and tries to acknowledge flaws to help a religion improve... like Dogma (I still can't believe Kevin Smith was shocked about the blowback the film got from his religion. Like no duh, you can't try to make a movie that's gonna appeal to stoners and christians like wha --).
That said, I will say there are some stories with biblical themes and parallels that're preachy af but are so, so great. Jojo Part 5 for example is one big Jesus metaphor and I LOVE how unapologetic the writer is. It's probably my biggest inspiration when it comes to writing religious stuff. That and that one Doom Patrol episode with the De-Creator. Like a Cockroach that sounds like Barnacle Boy quoting revelations while people get raptured while the episode discusses how religion can help people cope? Specifically the mentally ill? Yes please. More of that.
New Gods is another good one. I love how the characters talk like they're from the old testament and even behave like old testament figures. Just anything from Jack Kirby in general.
I think it's fine if a character is grappling with the gray areas of the religion as long as the writer doesn't go full blown apologetic and be like "EVERY SHADY THING DONE WAS DONE FOR GOD THEREFORE IT IS THE WAY! RAH RAH RAAAAAH!". I will say tho, I am fine if characters are flawed af and have some beliefs that need ironing out. After all, Church isn't for good people, it's for people who need it. Just as long as you say "this problematic thing this character believes in is obviously wrong" instead of being like "He's christian therefore he's immune".
Stuff like that.
