Saved by the Fans: The outcry from Crossroads fans on the imminent departure of Noele Gordon from the series in 1981 was followed by a reversal of the decision to kill Meg off - see also They Changed It, Now It Sucks!. May even have happened with Jill and Adam too - see Happily Ever After.
So Bad, It's Good: To some viewers; to others it was genuinely good.
They Changed It, Now It Sucks!: Some fans never forgave the series for axing Meg (there were protests outside ATV's studios and a "Meg Is Magic" campaign was started, with obligatory record) and others didn't take to the various revamped formats, particularly after the 2001 revival killed off Jill.
