The British series crossed the line in one of the later episodes into soap opera plot lines. The three nannies are well-played and are unique and different. Mattie is the solid, moral nanny. She must deal with the manipulative Mrs. McCluskey (played excellently by Kate Williams in this role). It's interesting to see how the households in upscale Berkeley Square run quite differently. The townhouses are really organized by the staff. Relationships between staff and employer is pretty well looked down upon by the upscale upper classes. The families are uniquely different. Hannah has a history and baggage. She is far more complicated and intriguing than the other two nannies. She must deal with Nanny Simmons (well played b Ruth Sheen). Then there is Lydia who comes from a small farming village and must work beside Nanny Collins (played wonderfully by Rosemary Leach). The cast is first rate but the writing is very melodramatic. The art direction and costumes are first rate.
