This is a really good show - far better than many of the things on TV. The acting is good, the characters are engaging and entertaining. It doesn't feel heavy or like it is trying to take itself too seriously, but has a solid story line which allows you to get to know the characters as well as the situation.
Unlike some shows, the scenes are lit well enough to see what is happening, and the actors speak clearly enough too, so you can actually relax and enjoy it.
Whilst there is some violence and swearing, it is reasonably mild and hasn't been added purely to shock.
Overall an enjoyable watch, and I hope they bring it back for a second season.
