This is not the Mulan legend (where she substitutes as a soldier for her aged father). It's just a bit of Chinese wuxia with invading hordes vs a female hero called Mulan (supposedly a kind of sequel to the original story). Some loved it, some hated it - maybe it depends if you like Disney-Chinese better than actual Chinese. I prefer the original stuff, but this is far from the best. Also the plot here largely copies that of the 2009 Chinese film: Mulan, Legendary Warrior, which IS a version of the original legend and better than this.
Production values are pretty good, effects not so much. We have panoramas of huge armies deployed but whenever fighting is going on, it feels like there are about a dozen people involved, if that. Fairly competently done though. The actors are OK, Mulan played as a bit too wise, passive and passionless for me, support average and the bad guy is certainly unpleasant. It mostly keeps moving along but has too many static prison scenes and too many where the princess arrives to shout 'Stop!' just in time to put an end to various cruelties. Didn't always make a lot of sense either - why does Khan, knowing he's under threat, have almost no security?
But it was reasonably entertaining, if not as good as the animated Disney Mulan. (I don't know about the live-action version of that. Not in a huge hurry TBH.)
