Absolutely adore the first movie The TV series and subsequent movies not as much but I do still like them a lot.
Also forgive me for my sin but... I like Yuna more than Lilo. The anime is actually pretty solid! Phew, there, I said it.
I really don't think people even try to like it. At least Yuna's and Stitch's relationship isn't a complete copy-paste of Lilo and Stitch like it is for Ai and Stitch.
