Citizen Kane Non Linear Structure

I think that the non-linear structure of Citizen Kane made the movie much more interesting. The audience was kept wondering what the meaning of rosebud was throughout the whole movie. This helped because is was the driving force of the entire movie. If the movie would have been in a linear structure, the motif of rosebud wouldnt have been so significant. I do not agree with the statement that Citizen Kane is the greatest movie of all time. I agree that the camerawork in the movie was amazing and the plot was amazing too, but I don't think that it is deserving of the title the greatest movie of all time. It definitely could have been one of the best movie of that time but I believe there are better movies now.
