One of Francis Ford Coppola’s many masterpieces, this took the idea of voyeurism to an entirely new level. It’s almost scary to see how incredibly easy it is to drop in on someone’s private life. The whole tone of the movie is downright disturbing. From the bizarre dark spaces to the ominous sounds, it’s never apparent what will happen. Gene Hackman gives one of his greatest performances, next to The French Connection it’s my absolute favorite. He plays a character so devoid of affection, yet somehow you feel compassion for him from the get go. No matter how many times you see it, there’s always something new to find.
