Bubble, bubble -- here's a list of 10 TV shows that are in trouble ratings-wise, from critical darlings that have failed to pick up enough of a an audience ("Community") to new shows that may soon be on the chopping block ("Pan Am").
Actually, we're surprised that more new shows aren't on the list -- less than half, four out of ten, fit intto that category, including "Unforgettable and "Prime Suspect." The rest have been around at least for a prior season.
