I LIKE the Darlings episodes. It's nice to see them in color for once. Denver Pyle is fine as Briscoe Darling and its always good to seen Charleen. The Dillards are always wonderful when they play and funny when they're doing nothing. The way Briscoe interprets their silence reminds me of Larry, Daryl and Daryl from "The Newhart Show".
However this episode suffers from some lazy and uninspired writing. The first half is good as the Darlings come to town and start to look for Mayberry brides and its great when they decide on Helen. But then the device Andy comes up with (in fact they way he finds out how to break the omen is very clunky) to counter the "Omen of the Owl" is pretty obvious and makes Briscoe a little too stupid. The episode also ignores Briscoe's previous interest in Aunt Bea and seems to forget Charleen's previous husband(s). You don;t expect such sloppy writing from the AGS. Perhaps everybody was losing interest now in season seven.
