I’m usually not a fan of historical military movies (Red Cliff etc.), endless combat scenes get old for me very fast no matter how epic they are.
And essentially Hua Mulan is exactly that but while most of these films are also all about manly men-bros and their bromances this is obviously about a woman joining the army even though it is forbidden (this circumstance/setting makes this one of the weird movies that feature a strong female main character but still only barely pass the Bechdel test).
It’s far more entertaining and dramatic then most other endless battle films I’ve seen and it’s a lot of fun to watch, so go for it.
