We found this nice comment about Liz in a review of Lost 3×16:
Gold acting stars for Elizabeth Mitchell, who is just so good. I could feel all of her emotions and see her pain, but I still couldn’t tell what side she was really on.
We knew since day one we loved that character, even when nobody trusted her… we had that feeling that we could trust Juliet, but after they started showing her past, it was impossible not to love her and feel for her, so it’s weird to read comments like this. She was in a cage, big as the island. She did what she had to do to survive, but it was crystal clear she was a pretty good person.
Elizabeth is just so amazing, this character wouldn’t be as good as it is if it wasn’t for the humanity Liz put in her.
