Vastly underrated
I think this happens to be one of the BEST Disney movies of all time. When I first watched it I wasn't keen because the trailers made it look smushy and kiddy, but I laughed all the way through it! My friends were the same when I told them about it, but I finally got them to watch it and they grudgingly agreed. They loved it! It's a modern, animated Disney film with lots of laughs and no sugar sweetness that you normally associate with Disney. The trailers did this film no justice.
The subject matter is so not Disney as well. It's refreshing to see people of another race/culture being portrayed without stereotype in a Disney movie (check out Aladdin, Mulan and Poccahontas and you see what I mean). Also, amazingly, it's not the typical 3.4 children, it's a dysfunctional family. Lilo experiences bullying, prejudice and behavioural problems as well as the care system. Nani plays the role of single mum and the responsibility involved, i.e. She can't just take off with the guy she likes, she has to think of Lilo. Basically it says that people aren't perfect, but they don't necessarily have to be evil for it.
And who can forget the unforgettable quotes from this film? "I'm so cute and fluffffffy!"
