I got this Blu-Ray to replace my old DVD that had always had a spot where it skipped. It was a good investment. The transfer is very nice, and one thing I feared might happen did NOT come to pass. When some movies get released on Blu-Ray, the hi-def picture can actually reveal problems, especially with movies that employed earlier versions of CGI. I was happy to see that while you could tell the movie was older, it still looked very good. That's great for me, because I really enjoy this movie and as a hero, Mulan is a wonderful character. She is one of few Disney princesses who does not have at least a portion of her being defined and/or heavily influenced by a man. While she is spurred to action by concern for her father, she is clearly not giving up part(s) of herself in order to please him.
As for 'Mulan II,' it was fun, but extremely predictable. The animation was nice, but the character animation was flatter than in the original movie, but that is, no doubt, a result of a reduced budget. Because time had passed since the first movie, though, the computer animation actually looked a bit better in places than it did in the preceding film. Sadly, I was not pleased by the absurd change in Mushu's character. While he had always seen the world through his own eyes alone, this level of amoral self-centered behaviour was a little obscene. It's to the point where you may be better off forgetting the second movie ever happened so it doesn't retroactively colour your opinion of the character completely.
I'm very glad I have 'Mulan' and I appreciate being able to see 'Mulan II' (I had not seen it before now), though I may just ignore it from now on.
