I admit that I have always been a sucker for a good post-apocalyptic story (with or without zombies). What makes this TV series interesting is its excellent production quality, particularly the quite realistic CGI and make-up of the zombies. Despite the subject, it is not at all an horror story (unexpectedly I didn't get a single nightmare after watching this, although I quickly realized that it was not a good idea to eat any meal while watching!) as it is rather about survival and how humans react and behave in extreme conditions. The writing is nothing exceptional but it is good enough to warrant excellent ratings, nomination for several awards and to be renewed for at least another thirteen-episode season.
