I read this threadt title at first as "Where are your favourite Disney canon animated films?" and I thought this was gonna be a "Where are they now?" kind of thread and I was so confused.
Evidently, this was not the case. So I'll just list my top 6, since honestly my list can go pretty long but I'll limit it for now:
1. Lilo & Stitch
-This film is probably my favorite Disney film just because of the subject matter it deals with, and also a partial bit of nostalgia becaue I grew up with this series. Lilo and Nani's relationship is well done and strong, and their interactions border on either being sweet, funny, or cringing because of how awkward/horrible something went. I also really love Stitch's interactions with them, as well as his own development he goes through. Lilo's story itself that she tells Stitch before he leaves is one of the most heartbreaking moments in a Disney film, imo. The alien parts are cool too, and sometimes very lolsy, but for the most part, what always worked for me was the Lilo, Nani & Stitch parts. Plus, the soundtrack tho.
2. The Princess & the Frog
-This film is my second favorite for a lot of reasons, and really surprised me when I saw it, because I was expecting it really like the movie, but not nearly as much as I did. Tiana is one of the most well-developed female characters from Disney, and all her motivations and character qualities are relatable, especially since she is doing everything in her power to make her dream come true. Naveen is actually one of my favorite parts as well, which is odd since I tend to be meh about the love interests. But Naveen himself is an interesting character and very flawed but goes through his own development. Ray and Louis are amazing "Side" characters (though I consider them mains since they're in practically the entire film) and I love how they help the heroes along in their journey and even go through some of their own character development, granted to a much smaller extent. Dr. Facilier is one of the most badass Disney villains ever, and I love how menacing he is, as well as how good of a manipulator he is. On one hand, I'm sad it takes pretty much until the climax for him and Tiana to interact, but their scene together is one of the best parts about the film as well. Oh, and Charlotte is one of the best best friends I have ever seen in a Disney film. She wants to help Tiana's dream come true just as much as her own, and she clearly goes out of her way to make sure her best friend is happy.
3. Mulan
-This film, along with Hercules, are probably the first two Disney films I have the most vivid memory of seeing when I was a kid, so I guess nostalgia plays a tiny bit of a factor here, but not as much since a bunch of nostalgia titles didn't even make the list. I think as I grew older, I grew to love this movie more, be it from the social class challenges it presents for Mulan as a female in this society, the way Mulan is willing to endanger her own life and possibly be killed just to save her father and protect her family's honor, and the way she interacts not only with the comedy trio, but with Shang and the Emperor. Overall, Mulan is one of my favorite characters ever, and I love her personality. I guess I'd say she's the Lightning Farron of the Disney films, if only because they both share the rep of having "no personalities/emotions" from the fanbase of each character's source material, which is evidently highly inaccurate, but also just goes to show that some people automatically think reserved characters = non-developed character. The songs are also amazing, and Make a Man Out of You is just one of the best character development songs I have seen in a Disney movie. Mulan's transformation scene is just so well done, down to the music in it to the imagery and symbolism it keeps using, and the fact that the reason Mushu couldn't wake up the dragon spirit is because it was already awakened and was in Mulan from the very moment that scene started.
4. Hercules
-This is partially motivated by nostalgia, but mostly motivated by the fact that I love Greek mythology (even if the film kind of screws that up majorly), and the fact that this is one of the few Disney films with a male lead who is actually well-developed. Hercules is one of my favorite Disney film characters, and honestly, a pretty perfect example of how you could develop Clark Kent/Superman in a film seeing as how the film is clearly inspired by Clark which is ironic since the Hercules mythology helped inspire Superman. Meg is also one of my favorite Disney female characters, as well as one of my favorite "accessories to a villain," since she clearly doesn't want to hurt Hercules, and when she realizes things are getting too extreme, she goes to warn him and save him, and does everything in her power, even when he wants nothing to do with her anymore. Hades is one of my favorite villains because he's so sarcastic and sassy (is as everyone in this film) and charismatic, and honestly, I don't really hate him as a person nearly as much as other villains. He's a terrible person, but even then, he's such a fun villain that I forget sometimes how awful he is. Phil and Pegasus are also some of the best side characters I have seen in a Disney film, especially Phil. This movie also has a Disney soundtrack I can listen to even without the context of the film - I just love it.
5. Big Hero 6
-I was really surprised by this film. I went in hoping it would be fun, and was not expecting any of the emotion rollercoasters I went through since I only saw commercials for the film, and never trailers. I saw Tadashi getting killed off, but that didn't make it hurt any less, especially since they built up his relationship with Hiro so well. Tadashi's friends were also a great touch, and I was so glad they were main characters as well, because they each were so unique and had their own flair, and I loved the fact that this was probably one of the few Disney films with such a diverse cast. Baymax is also adorbs as hell, and easily understandable to why he was marketed so much. But if there's something about this film that really gets to me, it's Hiro's development. Even before Tadashi dies, he borders on dabbling in things that are sort of frowned upon, but as the film goes on, we see Hiro dealing more and more with his personal darkness, and then we see it fully unleashed in the Destroy Him scene, which is, in my opinion, the BEST scene from this movie. The music, the colors, the way Baymax doesn't just force his way through Hiro's friends but actually thrashes and beats them. The entirety of this movie was surprising and amazing and I really loved just how character driven it was.
6. Zootopia
-This is a very recent addition for me, evidently, but after seeing this film, I just could not stop thinking about it because of all the different things it tackles in this movie. Judy Hopps is one of the best developed characters in this film, as is Nick Wilde. I didn't really know what to expect from this film because the only thing I had seen for it was the Sloth scene they showed before practically every movie I saw. This movie tackles discrimination in such an amazing way, and something I honestly didn't really expect Disney to do in such a way because it's not like it's in your face, but it's not the kind of subtle you can ignore - it is clearly showing how awful discrimination is and how it can affect a person, and the way that it can be heavily engrained in people and how much you can play up fear on people's misunderstandings. I'd say this is pretty much the X-Men of Disney films just because of how well it deals with that. That being said, the characters were all wonderful, the score was great, the animation was phenomenal, and the plot itself I really expected to end after they uncovered what was happening to the predators in Zootopia, but it didn't and it kept going and it did surprise me, especially with that betrayal which I should have seen coming but I didn't. Also, Judy's apology scene is one of the best things in this film.
