I actually like Mulan 2, I like all the Disney sequels, midquels and prequels. I consider them canon as I do with all movie's that end up with one or more of these three types of movies. Unless its like the dumb horror movies where its like Halloween 11, or Saw 8. Or they remake NOT reimagine, but remake a beloved classic- doesnt matter the genre.
But yes I like all three Princesses- I pair them with Ling, Yoa, and Chin Po. I also love the movie cause we see Shang and Mulan get married.
