It’s great to have “Dollhouse” back for a second season. The Joss Whedon project took awhile to gain its footing, and it seemed like a case of too little, too late. Fox would never renew such a low-rated show. But Fox recognized that “Dollhouse” had a promising audience that watched on DVD, and gave Whedon a second chance. The creator seems like he knows what he wants to do and how to do it as the second season gets underway on Friday. The show is still dark but it’s less confusing and funnier. Having been rescued from Alpha, Echo (Eliza Dushku) is more the hero instead of the victim. She is now under the guidance of former FBI agent Paul Ballard, who made a deal with the Dollhouse, and trying to right a past wrong by bringing down a notorious weapons dealer. In a second storyline, Dr. Saunders (Amy Acker better than ever) is trying to cope with her identity after discovering she is an Active named Whisky who was designed by Topher to replace the doctor Alpha murdered. “It’s a tasting menu,” said Whedon, who wrote and directed “Vows”. “A bit of everything we do.” “Dollhouse,” now shot in HD, looks better, lusher, and moves faster.
