I agree, might not get to that, but they tried to make it look sinister and I can even imagine the director telling them to sneer as they said their lines. It was just a comical scene that wasn't supposed to be comical.
I'll probably continue FTWD for the rest of this season, but I think I am done. That ending with the quote about bigger narratives is just not where the show needs to go. I don't know the comics, so maybe they follow that story line. I just think the smaller group where people you care about actually die (like Travis who was basically Rick at that point) and you follow them actually living in a zombie apocalypse. In TWD, we see a giant horde, but it's like it doesn't matter. You can have a gun fight within earshot and it's ignored. I miss the days of the farm scene with the barn burning and horde destroying everything. They did that at the camp in FTWD. It's nice to remember that while single zombies are easy, there shouldn't really be any permanently safe spots. There should be a lot more zombies at this point than people.
