The four seasonwide posts (linked above) contain a HUGE chunk of people talking about how much they want the show to be better but they watch it again and again and again because there's a decent episode in there sometimes.
IkeMoses specifically said that the only character he likes is "crossbow dude": A character that wasn't even in the graphic novel. He was created for the show. You don't see much fandom for Dale or Rick or Andrea.
Of that whole cast, ONE character is likable for a majority of the series? Even the Governor seemed to be a bit middling at one point but David Morrissey seems to be doing a LOT with his character, which might be a testament to his talent rather than the writing staff.
Every one of those posts contain criticism of every kind. It's a shitty show that shouldn't be shitty.
