uhm... this is not disagreement, but wonder. What WOULD it take to make them like each other?
See, most of my "I like her" or even "I love her" sorts of feelings have come from a basis of not really knowing anything about the girl. I just saw her, I talked with her a couple times, and she seems cute and/or cool. People go into deep relationships for this sort of thing, ESPECIALLY with the wrong person. So, to me, the dialog was poor at best, the directing was iffy, and the acting very blah, but the concept seems fine enough.
They hung out. Travelled across the galaxy (twice) together and then stayed for several days at least (possibly weeks) in a location where they didn't do anything but have leisure time. She saw him exposed emotionally over his mother, she felt his attraction to him. These things may not be everything it takes to form a solid relationship, but let's face it: these people aren't having a stable relationship in the long term. He's gone Jedi-ing most of the time and fighting wars. She runs her political office. They keep things secret and that sense of defying authority can go a long way to holding people together when they would other wise break up.
So I just wonder, what else do you think it would take?
