It is great to have a series in which there is minimal violence, no ridiculous language, and virtually no sex--how refreshing for a change!
The scenery has already been noted elsewhere as spectacular, and as one of the stars. While I agree whole-heartedly with this, it is the acting which impresses me. Alastair Mckenzie does a superb job of portraying a suave Londoner who is suddenly thrust into a job he neither wants nor knows how to manage. However, (and you can see this most clearly when viewing the whole series, one episode after another) Mckenzie manages to convey that here is a man who grows from being a "fish-out-of-water" to being the LAIRD of Glenbogle. Mr. Mackenzie does it almost imperceptibly by degrees. Great work!
The rest of the original cast is equally strong. It is indeed too bad that most of the principal characters left over the seasons.
