Well enjoy it while you can. I like the show and think it is just starting to get good, however tvbythenumbers.com says it will likely not be renewed (same for TSCC).
Sort of sad that the networks wont stick with something long enough to give it a chance. Also, putting shows on Friday night that are probably more popular with younger adults does not seem to help either.
By the way...ever wonder who has the boxes for Nielson ratings? I get the feeling it is mostly Grandmas. We did get a paper packet from Nielson once where I manually tracked my tv watching for a week (maybe it was two). I never got another one, guess they don't like people who watch a lot of programing like the Discovery channel and Food TV (for my wife). I think they only like people who watch network TV every night and love Crime Investigation shows (sorry, had to throw that in....I like them, but enough is enough).
