You do realize just because a threat occurred humans don't lose their emotions.
Who said; "Hey, lets have a show with no human interaction"? Not me. I said there is too much melodrama. Secret pregnancies, affairs, crushes and other bullshit made up the bulk of the entire last season.
Season 2 had a lot of needed character development, and a good amount of zombie stuff.
Really? It had T-Dawg lay around not opening his mouth and too much drama. It had anything but a 'good amount' of zombie stuff. The majority of the season took place in complete isolation, away from danger.
Not everything is run into town and light up zombies. If that's what you expect you're watching the wrong show.
Who said it should be? Because we don't want 85% Dawsons Creek, all of a sudden that means we want Paul Andersons Resident Evil with relentless shit happening all over the place? Since when was the zombie genre about 'lighting up zombies' in the first place?
The best zombie situations are all about survival and claustrophobia. Romero's cut off farmhouse, shopping mall and military complex were all covered in a blanket of creepy claustrophobia. This series, at leas the last one, had none of that. In Day of the Dead, the idea was getting to the safety of an Island and worrying about lesser, everyday things. The Walking Dead jumped straight ahead to that scenario of rudimentary safety, seemingly just so it could get its hands on bullshit melodrama.
