Well, when I know the book to a movie, I always try to make out what is different at first viewing. I don't know why and I can't switch that off. But from second viewing on I can see it as seperate entities and just enjoy the movie as a movie, because I know what is missing and am prepared for that.

I need to see it a second time soonish. Why did I have such a bad headache yesterday when the others went again?

And I am not sure how necessary stuff is for the remaining movies. Maybe you they will leave hout the whole WWW stuff and that is why it doesn't matter to know why they did it and that Harry gave his winnings to them and all.

I think we need to have seen all seven movies to understand that. And then I will need to interview Oliver, who never read the books and isn't planning on doing so, how he understands everything and then I'll explain what he is missing because he didn't read the books. Not that that will make him read, but still.
