I don't understand how you could even say that Citizen Kane is overrated. As others have mentioned, it pioneered many of the cinematography techniques that we think of as normal, every day effects and are completely overlooked. Not only that, but another thing people don't seem to like about it is there isn't any action, suspense, or even any real romance. This is a result of the movies that we see today that has to have at least one of those things in it. Citizen Kane is a story about a man and his life, his rise to power, and how it ultimately drove him to become a cold uncaring, bitter old man who died alone. If one can't appreciate the tragedy in that, they shouldn't be watching anything more complex than Power Rangers.
