Oh, my. You don't have True Grit as #1? It's a great western, but it also may be the best coming of age story ever made, with a 14 year old girl (played by a 14 year old actress), bullying Rooster Cogburn into submission. It walks the drama-comedy tightrope as well as any movie I've ever seen. Hailee Steinfeld and Jeff Bridges both turn in Oscar-worthy performances.
If you want to see a really good & recent movie on the evils of communism, watch Mr. Jones:

It is about the Ukranian famine of the early 1930s and the commie-symp journalists who tried to cover it up.
Another good one, but older & more obscure, is The Inner Circle with Tom Hulce:
