The introduction to Jeannie's evil sister was a great idea. Barbara Eden was 10,000 times more sexy with dark hair!! Too bad that her sister had to have Jeannie's blonde hair, in order to impersonate her. In any case, Barbara Eden proved that she was able break out of that one-dimensional persona that she usually has. Jeannie's sister is more fun to watch, because she has more gusto and more energy. Despite repeating the word "darling" too many times, even her voice is more fun to listen to. Ironically, the bad things that Jeannie's sister does are not much different from many of Jeannie's tricks. Jeannie, herself, does bad things under the guise of something good. In any event, this episode is great fun. I just loved Barbara as the "bad" sister. If only she could have kept the dark hair throughout the episode!
