You see, I'm not particularly concerned about changes to the book, in which I am not invested (and I approved of quite a lot of Jackson's changes to LotR because they made more dramatic sense than JRRT's version - at least until RotK, when, in the theatrical version, he ought to have cut the opening scene - which is just there to massage Serkis's ego - put scene at Isengard in its place, and finish the movie at the wedding.) Films have different demands than books. However, the first movie is far too long for its content and I suspect the other two movies are exactly the same.
