The show had a different type of humor. The poser guy losing his shit and getting offed without putting up a fight is "funny". Not laugh out loud "haha" funny, but it's humorous.

Some of the banter is funny but it's all very low key and dry humor. I think it works because too much 'actual' humor would kind of ruin some of the heavier and more brutal undertones. I enjoy how they managed to make the story feel really heavy and brutal without being overly gory

Well the problem with Carl from TWD was the point of his character being how developing in a zombie apocalypse made him not like a child. He was harder than a normal child; determined and almost ruthless. Even Neegan was impressed by him, and Rick sort of struggled with the fact that his son was not "normal".

I think the series got to that point, maybe? But they took super long to get there and then killed Carl off anyway, so that probably pissed fans off a lot.
