I saw the first two series on tv and thoroughly enjoyed watching them. Unfortunatley I missed the third series so decided to see if the 3 series were available on the internet.
Realising there was another series due to start I waited even longer.
I read the reviews on Amazon to see if it was worth paying the best part of £50 for series 1-4.As I have started from the beginning, I have not yet caught up to the end of series 4 but, my friend who also watches the show has convinced me it was worth the money (probably cos she'll borrow them from me in the future :0).
Worth the money in my opinion. There are hours upon hours to watch so I will not be bored over the Christmas and New year when the in-laws come round.
