Calling all cinephiles: Recommend your must-see movies! Anything from your favourite films to great flicks!

I've seen a lot of films in my time, and I am looking for some good suggestions on what I should watch! Feel free to please recommend anything you like (Even things that may seem like obvious suggestions)! Hopefully other people find this thread useful, and some find joy in sharing some good films. Thank you all! :) via /r/movies http://ift.tt/2tYXXAX
