Seeing a few people continually complaining about the show. Is it just boredom keeping you here? Perhaps you should stop watching.
I was impressed with the story line. As another mentioned, religious characters are often portrayed as delusional or extremely shallow in terms of a deep religious belief. And the priest: "Like monks before the Tudors." eh, a little off-color, but I've heard worse from a man of the cloth.
Anyway, these Ruth and Don had a depth to them. Seems like there's been some amount of thought put into them, and that thought was wrapped up into a story line about witness protection. Really, the wit-sec part of the story was pretty thin, but it served its purpose.
And we're watching the relationship surrounding Mary, Raf, and Brandy evolve. The sad thing is, as lacking in depth as it is, there are plenty of three-way relationships like this, and they're just as lacking. That's about how we can be sometimes.
"It will be a lucky man who divorces you." Fantastic!
