Disney movies center around the main characters by default because they're the most important figures in the storyline, so background characters get a few lines in the script but are otherwise ignored. But if you could see the story from a background character's perspective you'd see each enchanting tale a little differently.
For instance- The Lion King is descended from a line of murderous lions, so why would the animals he preys upon swear fealty to him as their king?
And, as this comic by Willie Muse shows, Sleeping Beauty is basically a tale about a rich prince taking advantage of a drugged and vulnerable woman...how's that for happily ever after!
