The first two seasons focused on the lives of the McGregors and the Blackwoods. Both of these families owned large amounts of land and had considerable wealth and influence, however, Oliver Blackwood preferred to get his own way at any cost, whereas Matt would be there to help his fellow neighbour.
Admittedly, the series lost a little of its charm at the end of season 2 with the departure of many key characters and actors including Oliver Blackwood who dies in the desert and Danni (Joelene) leaving the series to pursue other acting roles. Personally, Kristie Raymond didn't play the part of Danni as well, but this is probably because I was use to Joelene, the two actresses were too different for Kristie to be fully embraced by fans.
The story lines though, while predictable in the good vs evil, did surprise the audience with broken marriage proposals, loss of wealth and death.
This is the type of show I can watch with my family without worrying about sex, violence or language - which is a rare thing nowadays.
