This is a new cop show which started last night here in the UK, and it's rather wonderful.
Here's a quick synopsis.
http://www.bbc.co.uk/drama/lifeonmars/John Simm stars as Sam Tyler, a driven and ambitious young detective, determined to keep the streets of 21st Century Manchester safe. But after a near fatal car accident, he wakes up, dazed and confused, in 1973. Has he gone back in time? Is he in a coma? Or has he simply gone insane?
Not obviously science fiction (there's suggestions it might be), but it's well filmed (there's a lovely difference in filming techniques between the 2006 scenes and 1973 scenes which makes the 73 stuff look like The Sweeney), well acted and a huge break from the formulaic rubbish we're used to.
Worth searching for and giving it a look.
