I've waited till I've managed to watch the second episode of this new TV series before commenting on it. It's all too easy to get carried away by an opening episode, only to find that was the best you're going to get.
Thankfully, The Walking Dead looks to me so far as if it's not going to be like this at all. Instead, it looks to be shaping up to being an engrossing show that could - I stress could - be one of the best to have started for the past few years. It's not up to the quality of Dexter (how many are, though?), but it has a lot going for it, not least being an interesting group of characters. The production values are high and the apocalyptic situation in which the world has fallen is credibly mirrored by the scenes, particularly those set in the city, which are every bit as good as depicted in movies such as 28 Days Later, Dawn of the Dead, etc. And, unlike some of George Romero films, so far at least the characters don't act stupidly and do obviously stupid things - one of my main bugbears of the Romero zombie films, from Night of the Living Dead onwards. The acting is excellent too.
It will be interesting to see how this series develops. At the moment things are looking good, at least for the viewers, if not for the characters in it! I look forward to seeing episode three.
