give me some good movies

Pretty good recommendations so far! I'd like to add "Spiderman: Into the Spiderverse". It completely blew away my expectations! That's really an excellent movie!

Another great one is Klaus! It's hard to believe that it's all 2D animation.

If you've never seen anyhting by Studio Ghibli, then Nausica from the Wind Valley, Porco Rosso, Spirited Away, Howl's Moving Castle, and My Neighbor Totoro would be my suggestions to get started.
