The whodunit ITV drama starring David Tennant and Olivia Colman set on the Dorset coast is back for its final series.

As you may recall, the first series followed the tragedy of the murder of a young school boy found on the beach. Detective and local DS Miller (Olivia Colman) and newly stationed outsider Alec Hardy (David Tennant) were responsible for  finding the culprit, which happened to be very close to home. This series was extremely well received and it was all everyone was talking about.

Then came series 2, which followed the trial of the attacker. This did not go down as well. Seeing Olivia Colman crying for 8 episodes straight around the same old characters can get a bit samey. Luckily, they seem to have got the message and have introduced a totally new case and set of characters for this third series.

The episode begins with Trish (played by the heart-wrenchingly talented Julie Hesmondhalgh – lets not relive that Corrie episode, I’ve only just recovered) being found in a right state outside the Broadchurch police station. She says that she has been attacked and raped and is in a very fragile mental state. The show writer and creator Chris Chibnall apparently researched the procedures that occur when a rape allegation is made with great detail, as he wanted to do it justice.

You can’t go wrong with the Tennant – Colman combo. They had and will always have a very frank relationship and a blunt way of communicating, but it adds to the charm. DS Miller’s empathy and gentle nature contrasts DI Hardy’s naive, direct attitude in an almost Watson/Sherlock manner. However this series, whilst still bickering like an old married couple, they seemed to have mastered the art of working together, complementing each other’s skills.

I was very pleasantly surprised with this first episode, I feel like Chibnall listened and learned from series 2 and has introduced a new lease of excitement into this final case. They have managed to avoid the ‘Midsomer Murders syndrome’ by not including another death into the small town. Lets see if Colman has dehydrated via tears by episode 2.
