All things considered, cinema is an incredibly young art form. Even still, you would never guess that considering the sheer myriad of masterpieces that the medium has put out over the course of the last 100 years. From 1926 to the present, there have been too many generation-defining films to count, all of them proof that cinema—when done right—truly can approach perfection.
From modern masterpieces like Mulholland Drive to foreign classics like Metropolis, the biggest movie masterpieces of the last century are the reason why this is such a beloved art form. From the emotional to the hilarious, from the exciting to the slow-burning, from the experimental to the crowd-pleasing, it's all top-form filmmaking. For variety's sake, only one movie per franchise can be considered for this list. Other than that, anything and everything is fair game.
