I've been saved long enough to know that whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are good, whatsoever things are of good report, if there be any virtue, if there be any praise, think on these things.
I think the overall message of The Parent Trap is true- divorce for slight reasons is not good, also children prosper most within an intact nuclear family. They need a mother and father, and the vehicle to express these truths is pure and lovely. I don't think it gets cleaner than Disney circa 1960s.
