I guess these are too recent to be retro, but they are interesting in a couple of ways. Lewis shows that a good idea and good acting can give a successful follow up to a finished popular TV series like Morse, and that British detective shows, still following on the basics that Conan Doyle and Agatha Christie used in their novels, can compete with the more modern thrillers and US cop shows.
My review : (4 stars) With John Thaw gone and his likeable Geordie sergeant now an inspector, the success of the show was always going to be who they could pair Kevin Whately with. They could have used a heavy brutal cop to work with him but the writer was inspired to have a skinny, awkward, high-church, Cambridge graduate played by Laurence Fox. As the series progresses you can see where this character is being fine-tuned. His height and awkwardness are being highlighted by making his trousers and jacket sleeves slightly short. It's all very clever and enjoyable.
