These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Contested Sequel: Stitch Has A Glitch, while still not considered as good as the original, is considered better than the rest of the franchise because it keeps the focus on both Lilo and Stitch, instead of just giving Stitch the spotlight. As well as feeling more like a direct continuation of the original film and its themes instead of a spinoff with a Gotta Catch 'Em All theme to it. As such it does also catch flack from fans who do like the direction the television show took.
"Funny Aneurysm" Moment: In the ending montage, one scene shows Lilo, Stitch, and the girls dancing. In the background is a sign advertising the fictional airline Tsunami Air. A little less funny after the "Boxing Day" tsunami of 2004.
Girl-Show Ghetto: The film was able to avoid it and make a big profit during an era in which Disney movies weren't normally doing so well. But to do so, the marketing focused on Stitch, the only male main character (notice the distinct lack of Lilo on the poster at the top of the main page).
The scene in which Stitch acts like a giant monster in a model scale of San Francisco. Legendary Pictures made a movie of a certain well-knownKaiju fighting in both Honolulu and San Francisco with other monsters in 2014.
In one scene, Pleakley indignantly yells "Educate yourself!" to Jumba when explaining the endangered status of the mosquito species. In The New Tens, "Educate yourself!" has since been adopted as a Catch Phrase by politically active bloggers on websites like Tumblr, and it is now something of a Stock Phrase associated with the "Social Justice Warrior" stereotype.
Ugly Cute: Stitch, most of the aliens, and even some of the humans could qualify. Chris Sanders loves this trope.
What an Idiot: Lilo in Stitch has a glitch. Seriously, why does she never realize something's wrong with Stitch until the very end?!
The Woobie: Lilo. The poor girl has no friends, has lost her parents, she's about to be taken from her sister, and her "dog" runs away. And she just copes with it all somehow. Why does she get cursed so badly?!
And Nani, who lost her parents and has to try to get a job, act as a parent at a young age, deal with Stitch, and try not to get her sister taken away by social service. The way she sobs when Lilo is captured by Gantu is simply heartbreaking.
Stitch himself, after he is unable to fulfill his programming. Jumba comments at one point that Stitch must be so lonely without friends or family or even memories to look back on. The only person who is kind to him when he makes an effort to help out is Lilo, which also means that Stitch later deals with the guilt of knowing that his antics and presence is putting a ton of strain on the family and leading to their breakup. It gets even worse for him in the sequel, Stitch Has A Glitch, where he starts to revert back to his old destructive programming and will eventually die. Of course, he gets better at the end.
One of the most awesome things about Stitch is that he was designed to be, and in fact remains, Chaotic Evil, but still has people he considers to be family and friends whom he wants to protect. He is the ultimate counterpoint for any "evil can't care about people or control itself" argument.
