By what you describe, this seems like a week-by-week trial by ratings. The same thing was pulled with Doug around this time about 3 years ago. My advice is to tune in (and convince others to do the same) so that Nick can see that there is a following for Legends. I put the odds on getting a remake of Legends at 3%, while getting Legends back for a run on Nick over the summer: 25%-27% (being optimistic: 35%). Other suggestions: E-mail whoever is in charge of Nick scheduling and say good job. Like by the dozens. I'll try to dig something up on their forums.
