Resurrection's ratings have been in free fall and presently hovering around 1.4. By the end of season 2, it will only have 21 episodes. If the ratings continue to erode, it wouldn't be surprising to see it be canceled.
Resurrection had a good premise, but they didn't and still don't know what to do with it. Bringing in the bland Donna Murphy as a villain to counterbalance the overacting of Omar Epps and making Michelle Fairley evil for the sake of evil are just some of the bad moves they had made. It's like Lost minus everything that made Lost special. The plot is just too slow and too stupid.
I'm excited about Forever getting a full season order, but they, like Resurrection, need to make good use of the parameters they have established.
