1.) Citizen Kane
2.) Hollywood and American Film Class (Yes, I have never seen it before don't make fun of me)
3.) Welle's Cinematography, Editing, Sound Design and Storytelling techniques were all incredibly bold for Hollywood at the time, where movies were put out by studios in an often cookie cutter style and the director didn't have too much artistic control. The film is overall excellent and absolutely stands the test of time. Greatest film of all time? I'm not sure I'd give it that. It was certainly like nothing I've ever seen before but the plot didn't resonate with me emotionally as much as other film's Iv'e seen in the past.
4.) Verdict: 9/10, but who am I to judge Citizen Kane?
