Well, you probably already know the Gomer Pyle series, so I won't explain what it's all about. However, this season is a real departure in some ways from the other seasons. First, Gomer's buddy, Duke (Ronnie Schell) is gone. OK, I guess his other buddies can pick up the slack. Second, Gomer sings a lot in this season. It seems that every time you turn around, Gomer is singing. If you like Jim Nabors' or ballads by baritones, then you'll love this season. If not, you'll find yourself pressing the fast forward button pretty often. Finally, Gomer's and Sergeant Carter's roles in the show are quite different. In the earlier years, the show is based on Gomer antagonizing/irritating Carter. Carter would blow up and then somehow everyting would work out. But in this season, Carter is to a large degree the source of his own problems. He's the one who causes the problems--not in a comic way, but by his own vices. Then Gomer, through his flawless character, saves Carter. It's an interesting relationship.
One more thing: some of the basic story lines are very similar to ones from earlier years. Did the writers run out of ideas?
I don't write these things as criticisms, just observations. The show is still fun and worth a thousand laughs. It's good, clean fun, fit for the whole family.
