I include Cam and Arastoo on this list. Sure, Bones is a modern detective forensic show, but the very cool equipment and some of the plots have a sci-fi element.
In truth, though, what I like about Cam and Arastoo is not so much the sci-fi part but how believable I find them. The episode in which Arastoo's parents come to town highlights the couple's compatibility. Some men marry women who resemble their mothers. Arastoo is one of them!
Cam is somewhat more diplomatic than Arastoo's mother. But she is just as tough and independent. And Arastoo, at heart, is like Booth (and Sam from Sister Boniface) and his own father: a family-oriented guy who is somewhat more laid back than his girlfriend/wife despite his personal ambitions.
Arastoo gets upset with his parents in the episode but at his core, he is mild-mannered and big-hearted. His gentle suggestion that Cam forgive the woman who stole her identity (or, at least, walk away) is a good example of how well the two work together.
