Query: Wire in the Blood (5th season)

I've previously purchased and viewed the first four seasons of Robson Green in "Wire in the Blood" and find it one of my favorites of the British mystery genre. Only criticism is that "about" year four, and on into year five, more and more quirky little "tricks" and invasions of an aural and visual variety are making their way into the action scenes; as if the director/producer/writer cannot believe the story and acting will carry itself--in my opinion, a bad and debilitating decision. Leave it alone! Just tell the story and let Green perform his magic.
