Love that bionic woman. Not Jaime (Michelle Ryan), the lead of the NBC action-adventure. Sarah (Katee Sackhoff), the compelling renegade bionic woman who stole the show again in her return in episode three. Sackhoff outshines Ryan in every scene they share. Sackhoff, who plays Capt. Kara “Starbuck” Thrace in “Battlestar Galactica,” signed on for more episodes, but she should be the star.
