NBC has been showing faith “Life,” the best show nobody watches, and it paid off on Wednesday as the thinking man’s crime drama scored 8.1 million viewers, its biggest rating of the season. TV experts believe “Life” benefitted from the absence of “Criminal Minds” on CBS, replaced by the Emmy nominations show. But I definitely think it was Sarah Shahi sucking on a lollipop in purple panties and cowboy boots straddling her boss’s back in one of the opening scenes. Network TV doesn’t get much sexier.
