The lack of audience can change the shows' energy. On Wednesday night, Samantha Bee held forth without a full audience on TBS' "Full Frontal," the first of the programs to broadcast without a studio crowd. With only a handful of her own staff in the studio, she seemed looser, laughing at different points in the show's various segments - almost as if she was just trying out jokes on her friends. It made for a more relaxed presentation, one in which the show may not be everything, but at least it could go on.
