Turner is the writer's husband? Oh that explains SO much!!
The Turner family have the most horribly twee lines and their scenes are very clunky. The scene with them drinking beer could have been so much better. And why the constant use of Dad, Son, Tim as if the viewer can't work out the relationship between a boy and a middle aged man he lives with.
The only reason I can fathom is that it's the only acting he can muster. Tim isn't too bad, despite the excruciating lines but a scene with Shelagh is embarrassing as she acts them both off the screen!!
