Lucy is totally schizo on the original DALLAS. First five eps, she's totally wicked and a Lolita-type vixen who enjoys stirring up trouble. Pretty much right away in season two they morph her into the unlucky in the love super sweet girl who just wants to be happy, and they stick to this sweet angle for the rest of the series, giving her increasingly less and less to do, bottoming out in season eight in which she's barely part of the cast. Then they boot her off the show and rehire her three years later to hang around and do absolutely nothing from 1988 to 1990. Then they inauspiciously ship her away again. Charlene is not a great actress but I think KNOTS would have brought out her talents. The better writing and acting around her would have also improved her own acting, in my opinion, and her and Mitch would have felt at home living on the cul-de-sac.
