There are some ways to change the wave of something that is a medium. That's how the term 'game changer' is described. For a movie that would make efforts to go against the norms of a rom-com using that term is fair enough because they're going for something different. For Crazy Stupid Love, it's not really a rom-com where the characters would find their soul mate but more of a dramedy trying to get back together. And that's all it is.
