If you're up for it Kaz you really should see Life On Mars - I'd imagine it'd be up your street as, not only was it a cop show, it had a supernatural element to it too. There were a few quite creepy bits, although at other times they concentrated mostly on the cop show element. It's going to run to a 2nd series, which is kind of a shame as I hoped it'd be wrapped up in one season but I'm still looking forward to it coming back. Try to catch a repeat or rent it before the next season starts in 2007.
There's a bit of unfairness about the UK crime shows here - people seem to always rate the US ones more highly and while I'm no crime show fan generally, it seems to me people are overlooking the rich history of crime series we have in the UK. Callan, The Sweeney, Morse, Murder Rooms, Bird Of Prey, Cracker, Waking The Dead... I'd watch all of these in preference to the US ones, some of which have their good pionts to be sure but they often seem glitzy and a bit robotic - those UK ones I mentioned are grittier, more quirky and distinctive, and have much deeper characterizations; part of my enjoyment of Waking The Dead was about the interplay of the characters as well as the forensic stuff. In the CSI programmes the characters are a bit faceless and zombie-like and the shows are a bit soapy.
Like you I enjoyed Sea Of Souls, although the first season was a lot better. What about Strange, do you remember that? It was very enjoyable and a shame they cancelled it. I like stuff about demons and devils. My Catholic upbringing perhaps?! Most Haunted is just crap though.
