This is my six-year-old daughter's favorite show ever. My son who is thirteen admits to really liking it too, so the three of us have a good time watching it together. Of all the shows of the Disney Channel, this is the best by far. It's smart, cheeky, and funny enough for parent who might be watching the show with their kids. It also gives its characters enough credit to allow them to be serious and to grow and change. This is a big step for Disney because so many of the characters in their TV programs are rather one-dimensional.
The plot set-up of rich kids being cared-for by the nanny ( Jessie ) and the butler ( Burtrum ) rather than their rarely-there parents is old. There really aren't too many exciting things to be done with it. It works here because you like the characters and their relationships. The kids all need fleshed-out a bit, particularly the teenage daughter Emma. All the characters need to take a few risks, and I hope they do.
