Having grown up Disney-fied, and with a parent in a job that we were informed was lift threatening, I can say that I had a normal (or less than normal) fear of my parents mortality. We got the bed-time stories with all their grim life lessons (Dont eat candy houses while lost in the woods unless you're prepared to burn the owner in her own oven, dont let the local dragon know your a beautiful virgin, while sitting on a glass hill waiting for a dashing young man to sweep you off your feet -dont eat the apple that he's supposed to retrieve and thereby claim you with, youngest daughters and blondes always get the best husbands... etc)
Walt did a better job keeping the stories real than his brother (who in all fairness ran financials till his brother passed on and left him the business). Walt's Cinderella lost first her mother, then her father, and was left in the care of someone less than caring. The next time Disney studios touches Cinderella you only hear after the fact that her father died, and there's no indication that the lack of maternal caring from "the evil step mother" is because she is a step-mother, she could have been the real mother for all we knew.
What I do remember about my childhood experiences with Disney-fied stories, is the shock and horror in finding out The Little Mermaid does not get the dashing prince Eric, but turns into sea foam. (My poor father was screeched, cried, and pillow bashed out of the room by his three incensed daughters who had begged him to read the story which he warned us was not the same as the movie. It was the last bed-time story we ever got.) 4-6 years after that I had my faith in book-movie adaptations completely shattered. It was announced that Disney Studios would be tackling The Hunchback of Notre Dame. So I got a copy of the book and read it. I was 13-14ish my littlest sister coming up on 10. Fortunately alot of the more gruesome bits went over my head, but I was still aghast at the choice and full of wonder at how such a story could conform to the expectations of moral guidance and happy endings. Our parents took us to the cinema (A big deal for a family of 6 on a tight budget) and I came out wishing I had never read the book as my siblings enjoyed the farce much more than I did. I remember sputtering with rage in the car home that the only things of the book that survived to film were some incidental character names. The emerald slipper, which was my favorite part of the book, was out. Esmeralda's parentage and backstory was out. It wasnt even the same Paris! The church guy was made more evil, the hunchback less, the ending that was so poignant and moving because of its tragedy was tossed into a mass grave along with the bones of so many other stories. It was a long time before I felt that a book I loved being turned into a movie was a good thing. Ok, in all honesty, it was Peter Jackson who saved book-film adaptions for me. When I heard that there was a rummer that LotR was going to be made into a movie, I hastened to read it so that it wouldnt be ruined for me. By the end of FotR I was sold, my faith in movie makers restored. Well, not fully restored. However well Peter did with LotR, when I heard that Disney was doing Narnia, I cried and begged the gods of cinema that they not screw it up, surely they had seen what a faithful adaptation could do to a box office, surely they wouldnt cock it up... well, it wasn't as bad as it could have been. LWW almost lived up to my imagination, and I was happy to purchase a copy. But PC was less faithful and VDT was impossible to find on DVD -when I did find it, fortunately on a rental, it broke my heart again. Someone told me they are going forward with another, though I dont know which one they will kill next, I'll probably watch it with the same face I made that day I stood downtown and watched one of the historic buildings burn to the ground.
TL;DR
I learned to fear the power of social media to brain wash me and my peers more than I learned to fear my parents early or tragic demise. (Seeing as my parents are both alive and relatively healthy, and brain washing is rampant, I apparently chose the correct fear.)
