I have enjoyed every series of Luther. It is dark, at times nasty but it is always compelling. To be totally honest, I didn't think that this third series was any better than the first two series but it gained a tremendous lift in the final episode. It was the reappearance of the wonderful Alice Morgan, played with great relish by the excellent Ruth Wilson. Alice is a terrific character, psychotic with a touch of brilliance as she dominated pretty much every scene she was in and she is a superb foil for Luther.
Right now, Luther is just about the best cop show on TV. Idris Elba is a very strong prescence and it is impossible to imagine anyone else in the role. Let's hope there is more to come as there is plenty of life left yet but I'm not sure if Luther and Alice should become an item. In fact, they definitely shouldn't as their relationship would lose it's edge. Top quality drama at it's very best.
