Like a few great shows, the Flintstones didn't end on a particularly high note. Curious that Fred's father was never shown (or even mentioned) anywhere in the series, but we have an episode about Fred's grandfather. The story of Rocky's Raiders wasn't particularly engaging. It was logical that Rocky looked like Fred, since they were related. Why did Lt Reggie Vanderock look like Barney, when he and Barney weren't supposed to be related? Same question applies to the characters that resemble Wilma and Betty. All the actors did their best, but the subject matter was unappealing. The episode also had a noticeably different dynamic from the rest of the series. It comes down to personal taste. For me, this story just wasn't in the same league as all the episodes that preceded it.
