That's so cliché and I'm quite tired of seeing that. Just once, I'd love to see a writer have a character like Quinn who doesn't learn her lesson in the end. That in turn allows the player/viewer/reader to learn the lesson for themselves and on her behalf. The tragic hero is a thousand times more interesting than the one who makes the predictable turn at the last minute and wins happiness in the end. Quinn can flirt with making the change, but ultimately she does not. The audience desperately wants her to make the change, but that's exactly why you don't give it to them.
If it's not clear already, I hate Hollywood.
