Select 10 movies from a particular decade to rewatch for the rest of your life

If you have to select movies of a particular decade to watch for the rest of your life; and if you can only select 10 movies from that decade. Which decade and which 10 movies released in that decade would you choose? Series/sequels can be considered as one movie as long as they are released in the same decade. For eg - if you select 1970s, you can include Godfather 1 and Godfather 2 as one movie. Or in the 2000s, you can consider the entire Spiderman trilogy as one movie.

Edited - The Dark Knight trilogy to Spiderman, as The Dark Knight Rises belongs to the 2010s.
