13 episodes to tell a story that could be covered in 6-7 episodes. I'm on Ep 8 and sheer willpower will be needed to get me through the last five. It's a very cynical approach to series production. There's too much development of subplots that add very little to the central theme and storyline and serve only to pad out the length of the series. In this Ep 8, the police appear close to solving the case and yet there's still five episodes to go. Heaven knows what side streets we'll head down before a conclusion.
Should learn from the brilliant 'River' that ran just six, wonderfully scripted and acted, episodes.
