It's enjoyable because it is still the only show centered around zombies, albeit badly. It doesn't really matter how much they seem to ruin it with the characters, as we've seen every single one turn into someone no-one cares about, aside from maybe Daryl who lost a lot of points by banging the living zombie Carol. Each decision they make as a group is stupid, but as an individual it's even worse. They have no survival skills aside from when the odds are so heavily against them, the zombies seem to give in and just get massacred, rick cleaning out a prison with almost no light while being deranged, cutty claw-hammering the feck out of 900,000 zombies the other episode etc. They seem to have no sense of priority, or basic common sense either, like killing zombies before they group up and can force fences down, or just you know, simply fecking distracting them on the other side so they spread out. People have to make decisions that no actual person would ever make in their lives, like white-ponytailed gimp-leg deciding the best way to treat a bunch of dying infected people is to give them tea, by face-to-face visits, ensuring he is as close to them and in as much danger as possible to help them "drink their tea" because simply giving it to them and leaving isn't enough. Characters aside, the direction and writing is so amazingly poor that even based during a zombie apocalypse with more death and destruction than anyone can imagine, in a time where the subject has never been as popular, with the first show to really tackle the zombie angle, they are still focused on the shittest love stories and bullshit lame relationships that wouldn't be missed from any standard to shit tv show.
I'm still even haunted by stupid fecking things Lorie did or said, or in the case of last episode - new information that I have no problem relating to the old spastic Lorie - like how she made the shittest pancakes on Sundays because she wanted a family that ate pancakes on Sundays, but at the same time didn't want to be the kind of mother/wife that could make food for her family that wasn't disgusting to eat, despite making the same dish every week for....ever?
