How detrimental are cliches to a story? I've been planning a book for quite a while (I'm great at outlining but perhaps to an obsessive degree) and realised that my story heavily relies on prophecy, an old trope that many people often say turns them off a book. I've been too focused on making sure the story is cohesive and that the characters are interesting, but should I be at least thinking about changing the prophecy of the chosen one and making him more of an unfortunate who stumbled upon his quest?
