Just to clarify--if it's got space aliens in it, it's science fiction.
Which brings us to Lilo & Stitch.
What, you don't think so? "It's a Disney movie!" you protest. Well, try this on for fit, Thomas:
A genetically-engineered space alien designed to be an unstoppable force of destruction escapes its prison and steals a rocketship, crash-landing on Earth, where it is befriended in spite of itself by a lonely little girl who thinks it's a dog. Her patience and faith in him change him from a rotten little monster into a heroic figure as he saves the girl from the aliens who had been sent to recapture him.
Sure sounds like science fiction to me. And as an added bonus, there's hula.
In case you don't have children, or just felt that animated movies were beneath your dignity, and so managed to miss this gem, here's the synopsis:
An intergalactic jury is convened to pass judgement on Dr. Jumba Jookiba, a four-eyed scientist (literally) who was caught creating mutant monsters. Highly destructive, virtually unstoppable mutant monsters. One of these creatures, known as Experiment 626, is presented as Exhibit A at the trial, and scandalizes the room with vulgar displays of naughtiness. 626 is condemned to exile, and Dr. Jookiba is sent to prison.
However, 626 manages to break free, and comandeers a police space ship. The red one. Under hot pursuit, he wreaks havoc on the fleet before jumping into hyperspace. His escape is not entirely complete, because his ship sustained damage, and he crash-lands on a planet known to be an intergalactic wildlife sanctuary for the protection of the endangered mosquito, which prevents Police Captain Gantu from simply blowing the planet and 626 out of the sky.
At first is seems that 626 is going to land in the middle of an ocean, and thus, drown, but--against astronomical odds--a tiny chain of islands appears, and he makes landfall on one of them. Because retrieving 626 is going to be a delicate operation, the Grand Councillor of the Galactic Federation makes a bargain with Dr. Jumba--his freedom in return for the mutant. Jumba is sent along with Agent Pleakley, the "expert" on the mosquito sanctuary, and ordered to keep a low profile and not to interact with any of the sapients on the planet, which is called "EEarteh."
626 survives the fiery crash, and with a plasma gun in each of his four clawed hands, proceeds to make his way through the Kauaiian jungle, only to be run over multiple times by some tractor-trailer trucks bringing sugarcane to the mill.
He comes to in a dog kennel, where the other occupants of his cage are cowering in terror in the corner. He finds the flimsy chain-link little challenge and is about to scuttle away when he is narrowly missed by blasts from Jumba's plasma rifle. Realizing that he is safe as long as he has a human as a shield, 626 returns to the building where he draws in his more alien appendages and pretends to be a dog. A very eccentric dog.
He is soon adopted--for two dollars--by Lilo, a little girl who is having trouble coping since the death of her parents in an automobile accident. She gets onto fights, disobeys her sister, and emos-out to Elvis Presley records.
To call Lilo "imaginative" would be an understatement; she's more like Calvin with a mean streak, and in the horribly ugly and weird ("He was dead this morning!") 626, she finds her Hobbes.
Or more appropriately, her hob-goblin, because it is immediately apparent to everyone except Lilo that there is something very, very wrong with that strange blue dog. He's kind of like a sociopathic Snoopy, and rather than providing Lilo with companionship, he makes the situation worse for her older sister Nani, who has been trying to run the house and take care of her sister.
When Jumba and Pleakley, wearing the thinnest of human disguises (think glasses and wigs) try to grab 626--now called Stitch--at the tourist luau where Nani works as a waitress, the resulting melee causes her to lose her job. To make matters worse, a scary new social worker arrives and warns Nani that she needs to get a job, or else he will have to remove Lilo from their broken home and place her in foster care.
It does not help that Stitch is a destructive force of un-nature, which he graphically proves to Lilo by meticulously constructing a cityscape out of books and toys,
