Was it just lower ratings that go the show cancelled?
I'm wondering if part of the reason was all the internal strife--the kids wanted more money and more control concerning the story lines (always have heard they wanted more musical episodes), plus Robert Reed was becoming more difficult. I'm thinking if all had been well on the set, they would have gotten a 6th season.
