Scouts Out! Cavalry Ho!
I understand what you mean; but, I found that episode really something special. Michael Rooker really showed his acting chops and I went from hating Merle to being sad that Merle was dead. That is the quality of the acting and writing that can make a person change their opinion so much about a character.
I really liked Merle's character for one other reason; and, that is that he was honest about the situation that they have found themselves in. And, his love for his brother which led him to make the ultimate sacrifice in order for Daryl to be safe (or safer since it is the zombie apocolypse and how safe is anyone).
So, Merle's redemption episode was just great; but, I will miss the one character who can be honest with Rick.
