This movie has a lot of problems so I'll just go through the most annoying.
This film goes by way too fast, it's like a bad YouTube edit. Most of the actors suck, Nani in particular is really annoying. She has no chemistry with Lilo in this, so they never felt like a family who cared about each-other. The effects are mostly trash, while Stitch looks alright in this, especially compared to the 2019 Lion King, Jumba and Pleakley look awful. I feel bad for the CGI animators, imagining having to look at these things for hours everyday. This movie also took away a lot of the edge that was in the original, Lilo was a sweet but kinda messed up kid, that's the point, it's part of her arc. But in the remake, they water down her flaws. They also make the ending too happy, yet it also doesn't make sense. I know that sounds weird to say about a Disney movie, "oH, iT's ToO hApPy" but hear me out. In the original film, Nani raises Lilo after their parents die, it's even hinted that Nani gave up being a champion surfer to do it. Still, they learn to make the best of it, especially since Nani loves her sister and doesn't want social services to separate them. In this movie, they're just like "Oh it's ok, Lilo can just stay with the nice neighbor lady, and Nani can go to college in California because there are no colleges in Hawaii apparently", like fuck off. Plus, we don't know the neighbor that well, so this doesn't hit like they think it does. It also raises some questions, like if there's a neighbor who can look after Lilo, how come she's not babysitting Lilo more often. Why is Nani bringing Lilo and Stitch to these interviews when they keep messing it up. I know the idea is that Nani is too proud to ask for help, but if we don't see or care about the neighbor lady, then why would we be happy when she adopts Lilo at the end. Hell, what we do see of her makes her really unlikable, this lady straight up gets a dog without Nani's knowledge! What's wrong with this woman!? Overall, this movie sucks, don't bother watching it.
