I can understand people truly disliking episodes in season 7 and 8, because those were really bad; but when I see people rating 1/2/3 on episodes like this it blows my mind.
I wonder, what are these people expecting from this show? It often feels like they expect this show to suddenly stop being a tragedy, they want everyone to live in peace and be happy forever, they expect characters to be all impenetrable, cold and make great decisions all the time; but that's never been how TWD has done things, never.
This episode was great, it was really tense and you just knew someone was not gonna make it. And people acting as if Carol has never made any mistakes; if anything, Carol's character has been one of the most consistent throughout the show, she always gets lost on her own desires and puts people around her at risk.
