The Apartment
Though credited as a romantic comedy, The Apartment could surely fall under the category of "dramedy." It follows an insurance clerk who allows his senior advisors to use his apartment to meet women behind their wives' backs. The Guardian hails this one as the sixth-romantic film of all time.
Wall-E
Wall-E came out in 2008 and grossed over $533 million. It follows the story of a lonely trash-compacting robot who was left alone on an uninhabitable planet. It's an allegorical tale of what would happen if the world were to decay.
