I think it's worth at least one watch. Lots of fun Crouching Tiger Hidden Dragon esque kung fu scenes.
The biggest problem really is Mulan being a Mary Sue.
Why does that make it worth a watch? There are lots of CTHD-esque movies/shows, some of them are actually a bit more than a blatant cash grab, and close to zero of them give money to the absolute trash fire that is the Disney corporation.
