Citizen Kane vs. Speed Racer

To a certain degree, the movies Citizen Kane (1941) and Speed Racer (2008) sit on the opposite ends of some sort of spectrum for me.  One is a movie I acknowledge as one of the greatest movies ever made, but which I don’t particularly enjoy watching.  The other one is the film that I’ve described as “the worst movie that I ever thoroughly enjoyed”.  Guess which is which?  And which one shall I actually write about in this post?
