This has nothing to do with animation, but I'm indulging myself.
As much as I love animation, my favorite filmmaker, bar none, is John Ford. While there are many movies I like and watch repeatedly, I return to Ford's films more than those of any other director.
TCM (which I unfortunately can't get in Toronto) is having a 22 film retrospective of Ford's work. I think that these days Ford is an acquired taste; he's terribly different from contemporary directors and his films are now at least 40 years old and suffer from changes in social attitudes (many of which needed changing). But if you can respond emotionally to Ford's work, you enter a universe where everything is an expression of his personality and every film echoes and reverberates against every other.
If you're not familiar with Ford, try the Bogdanovich documentary Directed by John Ford airing Tuesday evening. After that, dip into Stagecoach, They Were Expendable, Fort Apache, She Wore a Yellow Ribbon, Rio Grande, The Long Voyage Home, Wagon Master, The Last Hurrah and Judge Priest.
