the question there is, which way’s the right way?
My thought was that there will naturally be discussion of HBP the book within the discussion of HBP the movie - at least, that is always what happens to me after a HP movie comes out. There’s the inevitable, what they left out, how they brought things to the screen etc discussion. If need be, we can have a HBP book thread now and another one in January when we would get to the book, following the one book a month plan. However, I too am in favor of reading them in order (and not skipping books… though if skipping them the first time through gets someone to read the rest of the series, it’s OK so-long as they actually read them all the second time through).
