So many ways they could of gone with this, but no go the doom and gloom way.
I must be the only on on here that likes happy endings.
I like consistent endings. With that setup, they'd done it very well to ensure there was no truly happy ending that made any sense. Torchwood gave the children and their families a 'happy ending' at enormous personal cost. That was the whole point.
The thing that would have ruined this series more than anything else would be a reset button happy ending to those fantastic 4 setup parts. That's what I was dreading. And I'm very glad we didn't get it.
