Well the thing about making books into movies is trying to get all the pertinent information on screen. To take a 3000 page novel and compress it down to a 120 page script (the average length of a movie script with each page amounting to one minute of screen time) then you can see the delima where not everything can be put on screen. Even at three hours and twenty minutes I'm sure Jackson couldn't get it all into the last movie as well.
I never read the books so I can't judge what should have been in or not from the books. But from what I saw, I think Jackson did a damn good job. 
mrmacca: You mean to say you sat thru almost twelve hours of movies in a theater? Wow! Talk about stamina!
