While I enjoyed Mushu and the cricket in the animated film, I did not miss them in the live action.
I much prefer animated Mulan not being a natural soldier and having to work hard and use her brain. I don't know if Mulan having chi is truer to the original legend, but it made the story less engaging for me.
I did very much like Mulan having a younger sister. I don't like how fictional characters are disproportionately older siblings.
Although Mulan having a younger sister made me think about what kind of effect Mulan had on other women in her culture, which I never really thought of before. Does her existence change other women's lives, or is she just a special exception?
Which leads me to the witch character. I was very intrigued by her, but I don't know if I thought she was a good idea overall or not.
I love that Mulan's father is supportive in both the animated version and the live action. I like how live-action Hua Zhou remained proud of being a father of two daughters even when his lack of sons would lead to his death. But animated Fa Zhou's relationship with his daughter makes me cry - even as an adult. Live action Zhou didn't manage that.
That's all I have.
