Although most people think animation movies are for kids only, I don't think that's necessarily true. Take "Nocturna" for example, it is so beautifully made that it can certainly entertain adults as well.
The story is about a little boy who can't sleep because his star has disappeared. He goes to the roof and meets the cat herder who he than tricks into taking him to the boss of Nocturna, Mocha, who lives on coffee. No one seems to care, but eventually he gets the chance to save Nocturna from it's downfall.
Although it is obviously a story for children, it's still
original and amazing to look at. I've seen it a couple of
times and haven't gotten tired of watching this pretty jewel
of a movie.
Here's the trailer:
