Dollhouse

Spring tryout “Lie to Me” started strong but has faded since losing its post-”American Idol” perch. Still, there’s a good shot it will be back next season. A longer shot at returning: “Dollhouse,” which has posted predictably low ratings on Friday. But Fox executives are holding out a glimmer of hope for the show, noting its loyal core and its strong DVR numbers. The April 19 premiere of animated comedy “Sit Down, Shut Up” was less impressive, though it’s too soon to talk about that show’s future.
