Always enjoyed Misty/Kasumi's role on the show. Her character definitely dropped a little bit in Johto, but not to the point of making me too bored of her character. First tsundere I saw and although I admit she could be a complete b**** at times, she really seemed to give off a believable, enjoyable personality. Misty matured over the course of the series greatly, and that was fun to watch. :)
So, yeah, I really liked her and her role on the show.
