1. the CG alien designs.

Kill them. Kill them with hellfire.
2.
...did this guy....SWEAR?! In Lilo and Stitch?!
3. The scene where Lilo meets Stitch. Mr. Inglebard's English class is now in session, because we're going to do a little compare and contrast.
Notice how, in the original, Stitch tries to blend in at first, but breaks character by reciprocating Lilo's greeting. Also notice Lilo's reaction: slight shock, followed by awe and wonder, because she's a weird kid, so it's not like she's going to be super-shocked by the fact that this apparent dog can talk. Now the remake:
Stitch tries way too hard at blending in. Panting, licking Lilo's face, the works. And Lilo.....screams?! Like any normal kid would upon seeing this creature?! Both of them are being completely antithetical to their characters here.
4. Who predicted that they would artificially darken Nani's actress' skin to placate the wokescolds?

Come collect your winnings.
5. The "ohana means family" scene. Again, let's compare and contrast.
Notice how, when Lilo says the line, Nani stops dead in her tracks and softens up quite a bit. By the end of the scene, things have noticeably cooled off. Now the remake:
"WE ARE NOT KEEPING THIS THING!" in comparison to the softer "we have to take him back!" of the original. Nani in general is much too aggressive here. And the scene ends with Stitch SLAMMING THE FREEZER DOOR IN HER FACE!
Lilo & Stitch was cruel as fuck, even though plenty of people love it to bits.
you want to talk about "mean-spirited"? THIS is mean-spirited!

WHERE IS THE MESS IN THEIR HOUSE?! THEIR HOUSE LOOKS SPOTLESS!
