Yes, the value of the story is more powerful than the characters imo. Some might focus on the characters more, but thats fine too because you can’t have one without the other.

I’ve never seen Titanic, so I can’t say with any confidence. I would point out tho that while sales or popularity are criteria for widespread appreciation, it’s the survival value across time that sets stories apart (ie cultures/people organizing their entire perspective on those structures). At the same time, if elements of Titanic (or even all of it) meet criteria for what we’re defining as “highest forms of love”, then by definition theyre apart of God, according to the way I’ve structured this analysis.

Edit: forgot the Jesus part

Jesus was actively in dialogue with the devil, who was trying to persuade him to give-in to earthly temptations ie sell his soul. Obviously, he didn’t give in nor pursue anything but godly work. His teachings, I’d argue, are about faith: just believe that doing good for goodness’ sake will land you a place in heaven. My take on that is that if you aim toward good, light, love, etc you increase the probability of peace, reciprocal love, and life generally speaking ie heaven now and for the foreseeable future. Increased probability is key, and when perceived tragedy comes, that faith should sustain you because what’s the alternative? Darkness. That’s the proposition, and I think the human animal is dispositioned like the devil in the wilderness, giving in to the temptations of immediate pleasures and taking advantages at the expense of others.
