To be honest, the first 2 seasons were magnificent. Season 3 was alright, but season 4 is just downright awful. Believe me, I used to be a die-hard fan, but these last 2 seasons just aren't as great to me for some reason.
The season premiere for the fourth season was absolutely retarded. Season one's opening scene set the story into motion, obviously. Season two's opening scene was great, they had just escaped the CDC & Rick made his final radio transmission to Morgan. Season three's opening scene was dead silent, the tension was extremely high. Then season four's opening scene is Rick... farming... for about a minute before the title credits began.
It truly is getting worse by the episode. I also thought it was SO stupid how season three's finale made a big ass deal over Andrea dying to save the Woodbury residents, just for season four to begin & kill off half of them? I'd be so much happier if badass comic Andrea were coming to life this season, but no. Everyone' getting swine flu & dying. Also, having Carol kill Karen & David was so sketchy. She obviously struggled killing that walker by the river when she was trying to fix the water supply, so for her to single-handedly take down 2 sick people who haven't turned yet is just ridiculous to me.
I know I'm probably get massive hate for this, but I just feel that the series has taken a turn for the worst. Every time someone in the group offers to do something, someone else is always like "No, you stay here," it's just all gotten so repetitive. I feel like they're trying too hard to add shock value by killing off so many characters this season, but it's really just not working out as well as the writers probably thought it would. Also, I'm not exactly sure why everyone is so in love with Daryl Dixon, he's just a lame attempt at the show trying to incorporate a "cool guy."
The comics are way better than what the show has become. So if you want some real thrills, go read them.
