Interesting, because I only read the story once, but I felt that one of the things she succeeded in doing was keeping Rodney's charm. I also felt the obnoxiousness and the neurosis were slightly overemphasized, but certainly not as badly as I have seen in other fic. However, I also felt that I understood why John was attracted to him. It was little things when they first meet, and later on their first date. John seemed to find some of Rodney's harder to take traits amusing right from the beginning, and he recognized Rodney's loneliness, because he felt it too. Plus, he was charmed in spite of himself.

While not precisely how I see the characters, the characterization wasn't something I didn't find believable, mostly because I bought the relationship.
