First of all, you will need to get over the fact that the lead couple look more like father and son than husband and wife. No chemistry at all between them, but that's really not a huge hurdle because this is not a romance. The story held promise, but eventually it became clear the writers really had no idea how to progress the plot in a believable manner. You will roll your eyes, and you will be disappointed. One part was just so ridiculous I had to watch it several times to make sure it actually happened. All revolves around a dark family secret that came about because of another dark family secret. It really should have worked, and in more capable hands it would have.
