I'm really enjoying Dept Q on Netflix:

https://en.wikipedia.org/wiki/Dept._Q

It's mostly a police procedural set in Edinburgh but has some disturbing elements of horror. Makes me think a little of Iain (not M) Banks at times.

The setup is the same as you've seen a million times on TV before: a newly formed cold case department digging up old cases from their files and all the usual cliches that come with it. But what sets it apart are the fantastic larger than life characters and dialogue. The subject material is dark and serious, but the dialogue is at times very witty and laugh out loud funny. I think my favourite character is Martin, played by Sanjeev Kohli [1], who you may know from elsewhere as Navid Harrid. Like Navid, he's a philosopher, but in this case formally so. Matthew Goode is remarkable too, playing a different personality to his usual roles.

There are some unusual design choices - it's set in the present day but architecturally and fashionwise it has a grungy 70s feel, reminiscent of Life on Mars (the UK version). And a couple of the cops look like they strayed in from a 60s sci-fi show being filmed in the next-door studio.

Overall, a very good show. But don't watch if you're disturbed by tension of the hyperbaric variety.
