As others have said, a marked improvement over what we had previously. I certainly liked this episode enough.
Only, there was one minor niggle that kept nagging at me: Wilf shooting moles? The man who never fired a gun? That seemed (to me) to be a disservice to Wilfs character. Whilst yes, things could have changed since we last saw them, that just seemed such an important defining characteristic of Wilf's character previously, to have been altered for "fun" in their old age. But, that's just me. I can accept it still, but it still nags at me.
