More Monarch of the Glen...

This weekend I just finished watching the third season of Monarch of the Glen.  That is all that is available here in the US.  I checked on Amazon.co.uk and they have all the way through the sixth season available.  So what is taking so long here??  I do have to say, that this season took a bit of a turn.  This series is pretty lighthearted and fun, but the last two episodes (there were 11 in total on this DVD set) were very much on the sad side!  I don't want to give anything away in case anyone might be watching these programs, but I wasn't too happy with how things completely wrapped up.  Of course they leave plenty of loose threads to keep you coming back.  Unfortunately I am not sure how long the wait will be for the next season.  I was a bit bad and looked ahead a little on the Monarch website.  Sometimes, I admit, I do the same with books...very naughty, I know.
