Spoilers oviously
My least favorite is Rick and Shane and my favorites are Daryle and Dale
Rick- He became my last favorite after sending Randall to the zombies
Shane- he became my least favorite at the start of season 2 and after that little insurrection there was no hope for him
Daryle- is pretty much just like me. The only different between me and him is are physical appearance
Dale- I respect him more than any other characters in that show. He was the voice of reason. I had even more respect when he defended Randall.
