The story arc from the beginning of series one to the end of series three is amazing.
I found some of the stories so very sad (don't want to say to much in case I spoil it for someone!) and yet it can be so funny too.
I love the way that no one's character is black and white and the way that the storylines are given so long to develop.
Plus several attractive and charismatic men to watch is the icing on the cake .
