Spoiler alert about the entire series!
Well I have finished and although on one level it was sort of light entertainments I think they were so wrong to overload with so many dramas and as I said before, the type of situations soaps use to boost flagging audiences.
I am sure all the "issues" they introduced ie racism, illegitimate children (under age sex?), rip off system, Pom hating, did all happen.
As they are so obviously hoping for a second series with so many plot lines left up in the air they could have spread it out a bit more, and looked at the culture shock, having to fit in, family tensions and even shown the impact on family left behind.
And if there is a second series it would be nice if with a whole bus load of new arrivals they could shift the focus to another family and bring up other issues. But suspect they will stay with the same family and it will remain a bit soapy.
My one niggle (in spite of other unlikely events) was could a man, anyone, dive in quite a bit later than someone with a rucksack of stones on their back, not only reached the depth they must have sunk to, got the rucksack off and brought them to the surface still alive.
