I can imagine a husband and wife breaking up over sharply diverging views on certain films, but why would they get married in the first place if they strongly disagree about the look and sound and soul of great cinema? I could never feel close to someone who disdains Zero Dark Thirty or I Confess or Manchester by the Sea or The Battle of Algiers. You can always smell where a person is coming from or how deep their passions are when it comes to film. It's not rocket science.
