CITIZEN KANE is continually listed by countless film studies as the greatest American film ever made. Is it? Maybe. I wouldn't be the one to tell. Is it my favorite? No. But it is an engaging, stimulating, and gorgeously made film about one man's flawed life and his constant search for meaning, which evades him to his death.
There is no violence or language. It is mentioned that Kane's political life is ruined after his extra-marital affair with his soon-to-be second wife, but it is fleetingly mentioned. Kane tries to buy happiness in all forms, and is very self-centered and controlling towards both of his wives. There is also some social drinking, and one character proves to be quite fond of liquor.
