Knowing nothing about this show, I decided to check out IMDb. I was confused as to why the rating was relatively high when the show was apparently just about a bunch of phone calls. I'm glad I decided to give it a try. Being a sci-fi fan, I binged watched every episode on my iPad.
The visuals are part of the story. You pick up pretty quickly that they are "Visual time streams." I found I could connect and anticipate plot points, not only by listening, but by watching how the visuals change. As the episodes progress, things become ever more interconnected. I believe the show was helped by having several well-known actors participate in it. They make it possible for the viewer to experience the most important thing with science fiction: suspension of disbelief.
Some reviewers have suggested just listening to the show, like an old radio serial. I believe it's much better to listen AND watch the visuals, because they help guide you through the events. For me, it turned out to be a really interesting way to experience something like "black mirror," but in a VERY different way. I think anybody can enjoy the show, but people who like science fiction with a touch of thriller will probably be its core audience.
Since it's not a heavy investment, each episode is only about 15 minutes, watch at least the first two episodes. By then you will know if you want to stick with it or not.
