@Robert Gentel,
OK, that makes sense.
Within the context of these kinds of shows (tween and teen girl shows), this is pretty unusual. These girls are usually all about the clothes and the makeup and doing various stupid things to attract boys. In this show, Carly is actually smart (she gets A's, is sad when she doesn't, and that's not seen as something that she should be ashamed of) and Sam is actually a tomboy in a meaningful way (she eats like an absolute pig and doesn't care what people think about that, she is TOO quick to resort to violence -- which usually is not approved of -- but can also be counted on to come to the defense of her friends when needed).
Sam is not a role model at all -- Carly's the center of the show and Sam is mostly comic relief -- but it's still nice to see the usual daffodil model being subverted.
("Daffodil" is shorthand from the show, but yeah I don't generally have much use for daffodils and definitely am happy that my kid isn't. We're about equally tomboyish.)
But I agree re: chips on shoulders and whining.
