The best show on TV?

So I'm now 4 weeks into the 8 week run of "Life on Mars". Yes, it's a British show, but it's a damn good one. The premise is interesting. Detective Sam Tyler is hit by a car in the first episode. When he wakes up, he's no longer in 2006, he's now in 1973. He still has his job with the police force, but he's confused. Is he really from 2006, and has time travelled to 1973, is he really lying in a hospital bed in a coma and dreaming he's in 1973, or is he from 1973 having suffered a head injury, believing himself to be from the future.

As the series goes on, it's quite clear which of these options is the more likely (although the clues could be placed there by his addled mind). It's a real fish out of water show, as although he's in familiar surroundings (Manchester), and in the same job, it's all different, which is one of the reasons for the name of the show (the other being that it was the Bowie song on the radio when he was hit).

If you haven't caught it yet, give it a whirl on BBCAmerica 10pm on a Monday night.
