Either I'm getting used to Stephen Tompkinson's portrayal of Banks, or he's softened in this series but he seemed much more believable. Also, the arrival of Caroline Catz as DI Morton, his sidekick, is a huge improvement on the Annie Cabot character of the 1st series. Catz's character has more depth and individualism than Andrea Lowe was allowed to be as Cabot. And the initial relationship was a fiery test of territory as they pace around each other, slowly arriving at mutual respect.
The story lines seemed stronger. Good support team. The settings are good and the series was on the whole greatly improved.
And I liked the incidence of Bank's actually getting it wrong in the final episode. It made him seem more human.
