I got caught up in it again, yesterday, while they were showing Season 1. I then remembered why I got so involved in this story. It really is a character-driven piece, even if a lot of people want more zombie gore. Hubby and I are not people who are into the zombie genre; but, we were bored one weekend and I had the entire first season on Netflix streaming, so we decided to try it and if we didn't like it we could just stop watching. We got hooked. But, that first season of 6 eps really was outstanding.
The show is definitely addictive. My husband and I have always liked horror movies, including some of the zombie genre, but in our opinions, The Walking Dead is in a class by itself. The zombies/walkers are almost extras, in a way. The character development is what gets so many people (including us) hooked.
