The Iron Giant
One of the last drawn animated pictures before it all just became computer-generated animated movies. Released in 1999 (for me the best year for movies ever) I still love to watch it every now and then because it's such a sweet movie told in a simple but very effective way about a boy befriending a giant robot and teaching him what it means to be a hero and in a way to be human as well.
Of course, there are some familiar things that remind me of E.T. (which is my all-time favorite childhood movie) but that doesn't diminish the movie in any way because he still has so many unique things to offer, from drawing style to the time the story is set to the amazing voice work.
