But Han's just "eh" in the first movie and in the second, downright--well, basically, if I were Leia I'd take a blaster to him. And then in the third--well, the end of the second and on--he gets some sense and is even kind of sweet. So yeah, I guess if you take it like the righteous man who ends bad vs the bad man who ends righteous, Han's (marginally) better.
Wait, no he's not. He's only sort of sweet for brief moments in the third, and you have to be a bit more grown-up than I
Anyway, R2 still wins.
