Not sure how my review will do this show justice but here we go...
We follow Tully and Kate over 3 different timelines - as teenagers, as 20-30 somethings, in their 40s - with each decade's storyline cleverly intertwining across each episode. The timeline jumps around but it is so well done that it isn't confusing like some shows.
The casting is brilliant, Katherine Heigl and Sarah Chalke work beautifully together, as do the younger actresses cast to play their teenage selves.
And yes I cried. I don't think I got through a single episode in the second half of season 2 without bawling. I had read the book so I knew what was coming but seeing it all on screen made it even more emotional.
I also cried at the lack of a Kate/Tully relationship in my own life. Never had a friendship like they do in the show and that made me sad.
All in all a fantastic programme that will make you laugh, cry and reflect on your own life.
Oh and Dancing Queen will never sound the same again.
