I think folks are spoiled rotten, and adult normal ball pythons are beautiful animals--so are adult morphs of all types. We have a preconceived idea of what we want them to look like, and when they don't grow up to live up to it, we get disappointed. That doesn't make them ugly.
It's funny, though--many people buy the best hatchlings they can, but they have no idea how well their colors will hold into adulthood. It's surprising more folks don't wait to buy adults, when they can see their true colors. I suppose if they did, though, all this wouldn't work so well as it does.
