Apart from the shooting (not a spoiler. It happens almost immediately).
This seemed to be mostly a drama about a getting the kids to school.
Too many side plots which were irelevant. The people trafficking piece was net even a good red herring as we already know 'who-dunnit' But also too many disjointed flashbacks which were never really concluded satisfactorily.
Disappointing, as I normally like Charlene McKenna. There will almost inevitably be a second series - but I won't be watching
