That's unfortunate. It's over. How does that happen so fast? It didn't even get a chance, right? Will CBS get better ratings with the reruns it puts in its place? That's right, the Stanley Tucci vehicle 3 Lbs has been canceled (apparently) after only three airings. The ratings of 3 Lbs declined every week, ending up receiving even worse ratings than the show whose place it took, Smith. Broadcasting and Cable has the whole story.
