I'm sorry but I have to keep it real on this one. Kate was one of those characters that I liked in the beginning, but over time she really started to irritate me. I felt like her character needed to make up her mind as to who she wanted to be with, either Jack or Sawyer. Now I am only judging her character on lost and not as an actress in a whole. She is a good actress; I just didn't like her on Lost. I guess I need to see her in another role outside of Lost before I can really determine how good of an actress she is but if I were basing her solely off of LOST, I would have to say she is pretty average.
