Exactly!
Once possessed by the books these thoughts occur after the movie.

So spoke my wife and daughter endlessly.....still going on days later...

I simply indicated to them that I appreciated that the departures which they had identified were in part due to having to fill more time on the screen than one has to do with the written text.
For example....A battle scene in the book:
"the battle raged for three days with massive struggle and bloodshed"

Would have to be transformed on screen to something looking like a three day battle. This means more action which means importing actions not found in the book.

Generally I approved of several of the changes. I noted that the great wall breech scene was a great motif no matter what siege one talks of from troy on down.

Generally not having been taken by the books I simply let the discussion pass saying only that I did enjoy the movie. I do believe that when movie theatres sell huge large drinks....and run long movies....they should issue bedpans or urinals....or maybe just install a convenient trough in front of the seats. I could also suggest that I dont need the free refill that comes with the purchase of a large drink
but I will simply re-fill the container myself....

Now ....that you have discussed the action....
what did you think of the music?
