how do you want it to end?
They've said before that the show will go up until around the time Rick wakes up. I hope they stick to that instead of dragging it out way further. So, to work toward that, I hope they continue killing off more main characters, and quit adding new ones.
I'd love it if it ends with a way that sort of nods to the original series. Maybe for a minute they feel like things have slowed down enough, or that they have gotten enough resources/weapons, and hey, someone's sibling is a doctor in the hospital that Rick was in, let's go find them. So we know they head off in that direction, maybe on a boat again. And somehow all die. I mean, really, I want them all dead at the end. That seems to be kind of the point, and while I like the story well enough, I can't really say I care about any of the characters on here. And then maybe just show the boat floating, with a map/plan laying out.
