I know that these two movies are not the best in quality but the impact they had on animation as a whole is felt in a lot of homes. Christmas classics like Rudolph the Red Nosed rain deer and How the Grinch Stole Christmas were the movies I was thinking about.
Wallace and grumet is another movie that made a big impact with the style it uses.
The Simpsons movie is honestly one of the best movies based on a tv show cartoon.
Beauty and the Beast and Lion King were two of the best 2D drawn movies made by Disney that I can think of.
I love the movies that have been mentioned on this topic so far! The book of life I definitely do not think is one of the best. It is average to me but honestly I enjoyed it
I had a very silly and very short sneeze story in my head just focusing on la muerte and the character very similar to Discord XD death teasing life's nose to win a bet
Out of the listed movies already said are Balto, Prince of Egypt, and Hunchback of Notre Dame are in the top 50
