How did Wednesday Addams' personality change over the course of the original television series?

Wednesday Addams' personality changed significantly over the course of the original television series. Initially, Wednesday was portrayed as a morbid and serious child who was often aloof and sarcastic. Her dark outlook was a stark contrast to her more cheerful and optimistic younger sister, Pugsley. Over the course of the series, however, Wednesday gradually became more open and friendly. She developed a close relationship with her cousin, Chachi, and showed more interest in activities such as sports and art. As the series progressed, Wednesday became more sociable and less serious, but she still retained her unique and individualistic personality. She also developed a strong sense of justice and was not afraid to take a stand for what she believed in. By the end of the series, Wednesday had transformed from a dark and mysterious child to a confident and compassionate young adult.
