Citizen Kane - What's the deal?

[Honus]

Citizen Kane is always put up as the greatest movie ever made, or some such. The first time I tried to watch it I quickly fell asleep. I was really tired that day, so I figured that was not a fair trial. I rented it again. This time I didn't fall asleep, I just got bored. The movie sucks, IMHO. It is unwatchable. What am I missing?

I've heard others agree that they didn't really like the movie much, but it was ahead of its time and that's what makes it great. Well, I'm sorry, but it came out two years after Wizard of Oz and Gone with the Wind, both of which completely kick Citizen Kane's butt.

Wizard of Oz is the best movie ever. I've watched it beginning to end probably 20 times and have watched significant parts of it 25 times. I never get tired of it.

The next best movie is The Godfather, which I can also watch over and over.
