Lori and Dale were the only two big deaths on the show that I found shocking and unexpected. The writing was on the wall for Shane, Merle, Andrea, Herschel and The Governor so I wasn't surprised when they bit the dust. As much as I enjoy Daryl and Rick, seeing one of them get ambushed and eaten by walkers would really kick things up a notch.
Part of why we all saw those deaths coming is because TWD kills off main characters. Not because it was just so expected and the easy thing to do.
I can't wrap my head around the only way to make this show good is to kill off Rick, Michone, or Daryl. I know that isn't exactly what is being said, but close enough. I hope Michone or Daryl goes, but not for a while. I just want to know it could happen. Don't do it for the sake of doing it.
I wonder how many people are hoping Rick, Michone, or Daryl will die. It's not always about shock value.
I think Rick or Daryl would be prime characters to kill off because they are very well developed, and their deaths could be totally unexpected AND shocking. I feel they are the only characters on the show who could die in next week's episode and leave me totally devastated, but unfortunately they are apparently untouchable. I am not nearly as invested in the other characters as they haven't received the same level of development. With all of the characters being either untouchable or under-developed, the show lacks suspense and has become less enjoyable for me.
Of course, I'd be just as happy if development and attention was more balanced among all of the characters. Carol earlier this season and Michonne in this past episode were steps in the right direction. I would love to see Tyrese, Bob, and Sasha get similar attention. Keep Glenn, Maggie, and Beth in the picture as well. I would love to get invested in everyone on the show, so any death could have the same level of impact without a character needing a "focus" episode before.
