I don't think you missed much. It was a verrryyyyy long movie.
When I was a kid you could see a movie as many times as you wanted, once in. I would spend all day watch Elvis movies. The only long movie I remember was Dr. Zhivago (ms I know) I don't know how many times I saw it. It seems like I was there every day that it run. I thought it was so romantic. Probably not what a 10-11 year old should have been watching but my mom didn't know and the theater didn't care.
