What is the best movie ever made?

I'm not talking about "OMG HAROLD AND KUMARZ GOEZ TO WHITE CASTLES! YAYAY81(!*#$!$)*" I'm talking thee ACTUAL best movie (in the English language) ever made. According to the cinematography, direction, acting, down to the extras. Out of the movies considered the best, which do you think is the best? Whether it be Citizen Kane or Shawshank Redemption.
