I'm going to go ahead and say that Dale is underrated. He seemed like an ass sometimes, but in my opinion he acted the way many people would do under those circumstances. He had some great moments, like noticing Shane' s evil side before anyone else did, saving Donna, his line to Rick about Shane ('That boy got problems' LMFAO), Agreeing to adopt the twins after Allen died, going out for gas in a very dangerous situation to help Alice when Lori was giving birth, coping on one foot, occasionally looking like Hershel and of course the whole arc leading up to his death with the hunters- How many people can wake up to find themselves part eaten and still find a way to laugh about it? 'Tainted Meat!' One of the series most famous lines. Also his reaction to both Ben and Billy's deaths were heartbreaking ('Who killed my boy?'). Have I convinced anyone yet? Probably not.
I agree with all this - Love Dale.
Also underrated is Rosita IMO, she seems like a great person and never has done anything to make people dislike her as far as I can remember- something barely any characters can claim. I'm still waiting on a Rosita-Eugene lovechild with beauty and brains.
I think she gets a lot of flack cause her best asset for survival in the ZA is her attractiveness... even though that's not a great place to be. She's also admitted to exchanging sexual favors for protection.... that's pretty hardcore, for both giver and takers. That behavior is another reason others might not like Rosita.
I agree though, she's definitely got some interesting potential hiding underneath the surface - hopefully she'll get more involved with the current story arc and Eugene.
