I enjoyed it but that ending was The Worst.
Re-watching the series recently I was thinking that Smithy would have had to have a complete personality/behavioural shift for me to be pleased if he and Nessa had ended up together: he was childish, narcissistic, misogynistic and phenomenally rude to Nessa.
Admittedly we heard today that he's been a good dad, but I hope that she pulls her hand back and says she was only joking.
