Here is a list of my favorite movies not not necessarily in this order. Some are from the sixties and seventies but some are not, take your pick. If I had to name one thing they all have in common it would be that they all question accepted beliefs of people at the time and are fun to watch. If you want to be depressed then that would be another list entirely.
