I don't know how two shows with the same premise can be so totally different. Perhaps it's the nannies. Supernanny Jo from Supernanny is a pleasant, friendly and outgoing young woman. All the nannies from Nanny 911 are stiff and icy, even with these young children. In one episode, Nanny Stella had to show the children how to hug and cuddle, and she looked extremely uncomfortable doing it. This was a family who seemed unable to show any affection, although they had 6 children under age 5. If you want someone to come in and TELL you how to do it, then you need Nanny 911. If you want someone to come in and SHOW you how to do it, then you need Supernanny.
