For me:
More scenes with Nadine and Krista.
Erwin is strictly a friend.
The bad boy subplot would be less predictable.
Darian is more in-the-middle - not a hero by the end.
Maybe make Nadine slightly likeable.
sharePut Stevie Nicks's solo hit by the same name in it on the soundtrack..after all, it DID inspire the title of this..
(same for Don McLean, AMERICAN PIE & Jennifer Lopez, LOVE DON'T COST A THING, to their respective songs movie namesakes..)_
Making Krista a bit more sympathetic. And showing that she actually likes Nadine and didn't mean to hurt her. Damn shame too cause Haley Lu Richardson is likeable presence on screen. And having a scene at the end with Nadine and Krista alone, and showing us maybe over time they can be friends again.
Agreed Darian being somewhere in the middle, he's slightly dickish but we see signs of him caring for Nadine.
