[TV Spoilers] So who are your favorite and least favorite characters on the TV Show and why?

I think my favorite character is Bernard, the way he is depicted he makes for a great bad guy.

I like that he acts all unassuming but is secretly pulling the strings, while a the same time we're shown that he too doesn't know everything but manages to hide the fact that he isn't all knowing.

My least favorite character is probably judge Meadows for lack of a spine and being a willing participant in the facade or perhaps Regina because her reading of her relationship with George feels "off" somehow, I can't place my finger on it and she ended up passing information to Judicial.

So what are your favorite characters or your least favorite and why? Please use a spoiler tag if you're going to make comparisons to book characters.
