Fox's low-rated drama "The Mob Doctor," starring Jordana Spiro and set and filmed in Chicago, ended its beleaguered 13-episode run this week.

I asked Fox Entertainment Chairman Kevin Reilly what went wrong.

"It was a confluence of things," Reilly said. "All I can tell you is every time we screened it for an audience either in a promo or the show, the audience said, 'We really like that.' It was actually a pretty good show. I think in the time slot it came on - against Monday night football and against "The Voice" at the high water mark - and then we gave it a title where, in the world of choices, a lot of people said, 'I'm not sure what that is or I'm not sure if it's for me.' And it just fell right through the cracks. It was really unfortunate. I didn't know whether it was going to be a hit or a not a hit. But I certainly thought it was a good show that would at least find an audience. It found an audience, but a very modest one."

Earlier in the day Reilly summed up the name of the show this way: "The worst title in the history of the world."
