SO HELP ME IF LILO ISN'T A GODDAMN MENACE IN THE LIVE ACTION REMAKE.
Least we forget Lilo is a problem child [ie: an autistic kid not being given the proper means of expressing themselves, or given any leeway for their behavior]. She NAILS A GODDAMN DOOR SHUT to keep her sister out of the house. MIND YOU-- CPS DOESN'T JUST SHOW UP FOR NO REASON.
Lilo had to have had a history of problem behavior outside [justifiably] kicking Mertle's ass. [Though her mom's absolutely a Karen and would call CPS on that incident.] Especially since Lilo bit her.
She feeds Pudge every day-- because her parents died in a rainstorm and she's afraid she'll lose Nani too, unless she feeds the fish that [in her eyes] controls the weather. It's all very reasonable logic for a six year old to have.
Lilo's acting out is also in response to losing her parents-- an extremely traumatic thing. Children aren't built to process that kind of trauma without therapy-- so her bouts of anger are her brain attempting to manage it. She emotionally disregulates all over the damn place in the original film.
No one understands her-- not even her sister. Leaving Lilo feeling isolated and alone. She cannot express herself properly, and she gets bullied by her peers-- furthering this feeling of being too weird to have a normal life. A common experience for neurodivergent kids. It's not as though Nani can afford to send her to therapy or get her evaluated, either. She's working full time and doing her best but she's not ready to be a mother. She's still a kid, herself.
SO IF THIS KID ISN'T A GODDAMN MENACE, THEN IT'S NOT LILO AND STITCH. IT'S JUST SOME RANDOM KID AND STITCH. The entire point of the film is that Stitch helps Lilo the same way an ESA would. He calms her down, helps her learn how to redirect destructive behavior [some of which she herself has exhibited in the past] and he helps her cope with everything she deals with.
Lilo would have been taken by CPS and separated from the only family she had left if that little alien goblin hadn't crash landed on her island.
