I agree with you to some extent but it's completely fair to want characters that make logical decisions and suffer consequences logically at every turn. The series has been completely yo-yo like in terms of its drama and science fictional elements. The first 2 seasons had a very good balance while the rest up until now haven't been able to find that balance. The series for me has been successful because of it's drama and characters not because of the zombies, that is part of the setting which drives the story. Like, people just wanting a zombie series will find most episodes boring and uneventful, while those that appreciate the drama and character study aspect as each episode unfolds will find the series enjoyable without the constant zombie attacks. With that said, its understandable why Glenn isn't as tactical as he use to be and is willing to risk he's life as he's experienced so many near death scenarios that he's fearless and willing to subject himself as bait. Or how Carol has become cold hearted, pessimistic, cruel minded, and relentless in her decisions even if she's wrong, because that's part of the evolution of her character. That's why the writing needs to be consistent. I try to watch every episode with the idea that it's just a zombie series, but it's so much more than that.
