I have just caught on to this show by watching a few episodes on a flight. I agree with what folks are saying here about the fluff dragging the show down, but I also know that that's the stuff that would get people like my wife into the show. She needs characters, backstory, romantic intrigue, etc. So maybe that stuff was put in to attract a larger audience.
It's really good, and I also like that I hadn't heard of 90% of this cast before. Some nice fresh faces.
We may curse our bad luck that it's sounds like its; who's sounds like whose; they're sounds like their (and there); and you're sounds like your. But if we are grown-ups who have been through full-time education, we have no excuse for muddling them up.
