A Continuation on 'Ordinary People?'

I have continued to break ground on the topic I opened up yesterday so I will continue to post my thoughts in hopes of further revelations. In my last post, 'Ordinary People?' I spoke of being attracted to characters without defining that attraction. So I will attempt to work towards that definition.

I can comfortably state that a romantic comedy's success does not depend on having a crush on the characters. I have enjoyed several romantic comedies without those feelings. And the one character that I do harbor crush-like feelings for--Glee's Rachel Berry--did not have my best wishes as she neared her relationship with Finn Hudson.

However, I cannot recall enjoying a single romantic comedy without finding the primary characters likable. I can't recall ever thinking, "Those characters rub me the wrong way, but I really hope they get together. They could use each other." Even those who have earned my pity have done so with some kind of charm (Little Children, Me and You and Everyone We Know). Have you ever found yourself invested in a fictional romance between two unlikable characters?
