And most of these deaths happen to plot devices that no one has much investment in.
Here's where I'll stop you. At least in the Walking Dead
the death's have been far from predictable. I'm sensing you haven't watched the series becuase they've killed off more than the typical "red-shirts," as we like to call them from Star Trek.
Several likeable characters have died. Sophia and Dale come to mind. While it was easy to see that Shane would lose it and be killed off the other two weren't as foreseeable.
Also in this season they've made one of the most likeable characters on the series - Andrea - much less so as she's seemingly switched sides for safety's sake. I didn't see that coming either.
