EDIT: I also find the perspective of people who liked the character initially but don't now very interesting. I wonder if anyone feels the reverse--didn't like her initially but now does?
In the beginning I didn't find her that interesting, then I liked her, and since last weeks episode 'Super Men', I love her! She has really convinced me as a good CSI and she's just a great gal that you'd like to see on tv.
She also gets more interesting by the week.
In the beginning I thought she was a lame Sara Sidle copy, and even though no one could win over Sara Sidle, Lindsay is growing out to be one of the better female characters on all the CSI shows.
Her willingness to learn, to strive for justice, her kindess, it all adds up.
