This idea that disabled people exist with one sole desire, one holy passion, one desperate fixation on an able body, is overemphasized and obsessively repeated. This doesn’t mean there aren’t any disabled people who want cures; even people who are pretty content in their disabled bodies sometimes wonder about life with a different body. But it often consumes the character’s entire purpose in the plot, with very few alternate narratives to complicate or counter it. It’s an old, uninformed, one-dimensional read on disability that burns on the stinky fuel of nondisabled fears.
