I've seen it a few times, but I watched it again today, and I would gladly watch it again tomorrow, or on any given day.
Citizen Kane.
A masterpiece of cinema, Orson Welles was on fire for the entire movie, a success no man could ever achieve again. It was his movie, his vision. He did almost everything on the movie, and that singular vision cane be seen. The phrase "too many cooks spoil the broth" cannot be used better than in the realm of film, and this show that it is true.
If you haven't guessed, I adore this film, and everything about it. It is sheer genious, and I emplore everyone to see it at least once during their lifetimes.
