Excellent acting from this mainly Northern British cast.
Unfortunately, it seems the reviewers who left low marks either didn't watch all episodes - as some admitted - or just didn't understand what it was about.
It's about Family, death, grieving, secrets, but mostly how the human mind can be selfish, feels unloved or unwanted - where it is quite often the opposite
Mostly it's about how different people brought up in similar circumstances can want different things, different lives and different outcomes and how some go for it and some stick with what they think is "right", even when they are not sure themselves.
It's about loneliness when you're have people around you as well as when you are on your own - and how some of us are happy with being in that situation and some are not
This drama is much deeper than it first appears and needs watching again if you didn't get it first time!
