I actually think G I was one terrible show but then again, I usually watched it so maybe they were doing something right. I think part of it, was the idea of a group shipwrecked was really good, and the cast was also good. I was a teenager when it was on and I must admit I had my fantasies of being shipwrecked with Mary Ann.
Actually "The Many Loves of Dobie Gillis" was unlike any show I have ever seen before or since, and was really good.
