Having read the other reviews here I was quite surprised about the negative ones, and the "too predictable" complaints. I find the cast to be really enjoyable to watch, and the stories are interesting and well written. Sure the chief is a little glum here and there, but overall he seems like a relatively happy fellow, even with the reasonable hope of a love interest. There is a minimum of forensic or medical nonsense that makes it hard for someone who knows a little bit about such things to watch without squirming. The interaction with the new DI in the most recent season is fun, and the character actors are very familiar to those of use who watch a lot of BBC. So for open minded viewers my recommendation is to not be put off by the negative comments.
