honestly the quality of the show has been extremely down since after the first season. that season was superb, I suppose because of Darabont and better budgets
AMC got cheap and they pace out good effects and interesting episodes because they don't want to spend the $$$ and realize that they have enough zombie lovers hooked that it won't matter
it's disturbing when the show in the last few seasons has had points where you see like 1 zombie action scene every few episodes
