Color episodes

I agree that the colored episodes were not as good, in large part to the supporting cast. Emmet, Howard, Warren and Goober were not asgood as Gomer, Barney and Floyd. Another factor was Opie was getting older and was not as much the cute little adorable kid that he had once been.

Andy in later episodes

I believe I once read an interview in which Andy said he really missed Don and just didn't have the enthusiasm for the show as he did earlier on. It's a shame about their miscommunication and Don's commitments preventing his continuation; I think things would have been very different since Andy
