I started watching it but nothing ever happens, boring as fuck. Too much emotional struggles of the people, hardly any zombies and virtually no zombies getting killed. Rubbish.
I watched all of season 1 and had no idea what the point was of most episodes. They could have just said 'a policeman wakes up in hospital after a zombie apocalypse, then he meets some other people'... that was it. Then second season was the same, poor. Not their fault though, I read that Mad Men gets a bigger budget so Walking Dead suffers.
