I would recommend everyone to watch the movie with an OPEN MIND, please!!
The efforts into the set, costumes and the amazing Chinese backdrops are absolutely breathtaking!since they clearly mentioned that they are adapting the original ballad of Hua Mulan(not the Disney animated movie) where Mulan was actually trained by her father from young in martial arts but later was forced to adhere to Chinese conforms of marriage when she was of age.
So looking at that, other than slight awkwardness of Chinese characters speaking English which doesn't match their Rich Culture,
in my humble opinion, Niki Caro and the cast brought justice to the original story a lot! So be open-minded and bloody watch the film.
