I liked Lilo and Stich... ok, so there are things that I would change, but overall, I thought it was very fresh and funny. I laughed, I cried, you know the drill. It really was amusing in places, and I thought the animation was pretty.
Warning to parents though... it is scary for little kids in places. My daughter claimed that she liked it, well, you judge... her comment was, "I didn't very like it". She only liked the surfing scenes, but then again, she is a beach baby, so that might be expected.
