IIRC , the beginning of the end for me was the idiotic Book of Knowledge episode probably 5 or so seasons back. They played it up as some hugely important document some woman had that was key to survival. And they’re reading through it and listing stuff off and it’s like “How to Chop Down a Tree”, “How to Drive a Nail with a Hammer”, and “How to Bake a Pie”. And they’re all oohing and aahing over it like it’s the Holy Grail. That and Daryl quick drawing, shooting from the hip, and plugging a guy in the forehead from 50 yards and Idiot Coral picking off zombies with Annie Oakley trick shots were a little much. I mean, I can suspend disbelief for the zombies, but some basic stuff has to remain somewhat realistic.
