My parents are watching this show on 'UK TV', the cable channel that funnily enough plays British television shows. It's called 'Goodnight Sweetheart', about this guy who can travel in time between modern day London, and London at the time of the blitz during the second world war.
The show's good for one reason, really: the guy's so normal. He has a wife in both time periods and spends a lot of the show juggling them and thier stories. He tells the one in the past that he's a spy working for the British government. The one in the present thinks he's a dealer in blitz-era antiquities.
It's not that he's a bad guy, it's just that he's in over his head in something he thought he could handle. I haven't seen the whole thing, but I think he does end up deserting one of his wives for the other. He makes decisions, and not always the right ones. How often do you see that in a product made for entertainment?
