If you are attracted to shows that draw you to characters, this is excellent. The writers weave complex plots that one can pull together emotionally and that culminate in a meaningful way. I would have given this series a higher star score, but Nicola Walker becomes a burden to watch. She grows to be an unpleasant person whose life seems to be consistently under a dark cloud--and I think the actor brings far too much angst to the character. Aside from that strain, the series is well worth it, at least through series three.
