I will consider the Lord of the Rings one movie…because it essentially was.
-Keep the part in the intro where Isildur is seen entering the River and being shot by the orcs…this shows up in the extended edition (EE), and should have been in the theatrical release.
-Take the scene where sam and Frodo see Elves going to the Havens from the (EE) and put it back into the TR.
-Somebody other than Agent Smith as Elrond. I like Hugo Weaving. I do. But as Elrond? Sorry, no. My vote: Rupert Everett.
-Cut down the cave troll sequence. Instead, have Frodo stab it in the foot, as in the book, and then have the scene where Gandalf puts the holding spell on the door, and gets blown down the stairs by the Balrog’s counter-spell. And none of that absurd swaying drawbridge and “never toss a dwarf” nonsense.
-In fact, I was really bothered by “Gimli the wee little idiot” routine. Gimli was small, but had dignity, and was a fierce and deadly warrior, not some bumbling buffoon straight out of Snow White.
-Galadriel…where to begin? Cate Blanchet was a wonderful casting choice, but she was given shit to work with. The mirror scene was one of my biggest disappointments in the whole film trilogy. It should have been left as Tolkien wrote it. Her characterization as a vaguely sinister, vampy temptress was just absurd.
-“Let’s go hunt some orc!” GAAAAAH!
-Gimli the bigger idiot in Rohan: Come ON already! Enough dwarf humor.
-The Ents: So, Treebeard goes from the oldest, and among the wisest living things in Middle Earth to…well, a Wizard of Oz apple tree on quaaludes. The rise of the Ents against Saruman was THE best part of TTT, perhaps the final triumph of Nature over Technology before the long attrition of the Age of Men. The significance of this can’t be overstated, yet Jackson glosses over it completely, relegating the Ents go a comical bit role, that seems almost schizoid, given Treebeard’s sudden turnaround leading up to the attack on Isengard.
-Merry and Pippen throwing stones from Treebeard’s shoulders and crying “YES!” Stupid, stupid, stupid, stupid, STUPID! I would have ripped this scene out the spool with my bare hands had I known it was coming.
-Way too much time spent on the battle of Helm’s Deep, at the expense of other, more important threads (see Ents above)
-Elves at Helm’s Deep: WRONG! This is just dead fucking wrong. The Elves were no longer actively involved with human affairs, except for some nudging from Elrond, and the presence of Legolas in the Fellowship. This was important. This meant something. Obviously Jackson was oblivious.
-Gandalf’s reunion with Aragorn & Co. - Whoah, Gandalf, you’re back. Yep. Hey, how was death? Grooovy. Great, now what? We go fight, I guess. Cool. Another major letdown, drama-wise.
-Faramir: This character was completely destroyed. It’s hard to begin on what I would change, because I’d essentially change everything. Faramir in the books was perfect. Faramir in the films is a catastrophe. Horrid. This is the only change that actually disgusted me. It did, big time.
Frodo showing the Ring to the Nazgul: Fucking goddamn retarded. Pretty much the stupidest thing Jackson & Co. could have possibly done. It added NOTHING to the story, and introduced about half-a-dozen major conceptual and logistical flaws into the plot that were never even addressed, much less resolved. It simply should never have happened. Idiotic. Illogical. Bizarre.
Denethor: Give the guy a little dignity, will you? I mean, the film Denethor is just an oafish, cowardly asshole.
Frodo’s “illness” and the Havens: Well, Sam, my shoulder kinda aches, so, well, I guess I have to leave Middle Earth and the Shire forever. Yeah, I know it’s kinda drastic, but, man, it really smarts, I’m not kidding, and I hear they do some great Shiatsu in Tol Eressea. Now let me take ship with this big dopey grin on my face while you blubber away in tearful confusion, along with the audience.
Use the fucking books, you morons, and maybe half the world wouldn’t be asking people who actually read them carefully why Frodo sailed off in the end for no apparent reason.
