Best of the worst? Big fish in little pond?

Not sure what this article is meaning to say. It starts out saying how popular this new "terrorist reality show is in Iraq". Then, when mentioning it is on al-Iraqiya, which is funded by the US, it is on an unpopular station. So, it is a 'television hit', but, only compared to the dismal ratings of the other shows on the same channel?

"Terror in the Grip of Justice has become the most watched show ever on al-Iraqiya, an unpopular channel set up and funded by the Americans.."
