I agree with most of the above:
I’m sorry if the Scouring of the Shire is out (but I do trust Peter Jackson)
I think it would be good to have Sam wrap things up (he is the true hero for me, because he does it all out of friendship)
I always get emotional when I read the bit in the appendices about how Legolas and Gimli setting sail is the end of the Fellowship in Middle Earth
To those who want to see the Scouring of the Shire in the movie, you’re answering the wrong question. The question is not “Should the Scouring be in the movie?”, it’s “What should be cut from the books, in the transition to movie?”. It’s simply not an option to include everything. So if you want to see the Scouring included, what would you take out instead?
All that ring stuff really detracts from the action. They shoulda cut that, and put in more of Bill the pony. 
Chronos, if it really were a simple matter of trading some other scene for the Scouring of the Shire, I could come up with several good candidates. First off, elves (except for Legolas) are a total drag, so I’d consider putting Lothlorien on the chopping block. The Entmoot is also not likely to be terribly exciting or all that pivotal. And I think all the Appendix stuff would just end up being too much exposition anyway, so that ought to be right out regardless of the status of the Scouring.
I can understand Jackson’s concern that the Scouring would be difficult to deal with, dramatically speaking. But I stongly agree with the other posters who’ve already stated reasons for its inclusion.
Actually, Chronos, I don’t think the issue is one of not having time to include everything in the books (at least, that’s how I read your post; if I’m off, please let me know)–you forget that RotK is pretty short when compared to the first two books. I think PJ is axing the Scouring purely for dramatic (rather than time) reasons.
i would finish the movie the same way as the book enden. in my particular case i was pretty Disapointed wen i figured out that in the movie they missed parts of the book
Cinematically, the logical wrap-up is to have Arwen and Aragorn get married at the field of CarmelKorn during the big feast celebrating the victory over Sauron and the saving of Sam and Frodo. While it works in the book, it’s going to be pretty anti-climactic to watch the fellowship disintegrate for 45 minutes.
The very last scene in the movie will be Sam sitting in front of the fire and reading from the Red Book to his kids. In fact, it will turn out the the entire three movies was, essentially, Sam telling the story of “What We Did in the War of the Ring” to his children.
Remember, you heard it here, first!
If I were directing the ending, by the end I’d of kill off about 80% of the cast in heroic and/or accidental deaths (can you tell I read/watch a lot more horror than fantasy?)which Frodo would have to endure quietly, even though he felt a tremendous amount of guilt; especially when it’s something stupid he does that gets Samwise killed.
He’d of destroyed the ring after an epic power stuggle, then return home, embittered, and bemoaning his fate which just seems so anticlimatic and ordinary after all he’s been through. As he deals with his loses he tries to settle down with some cute hobbit woman, but he’s haunted by a sense of futility that eventually causes him to take both their lives in a murder-suicide that scandalizes the shire.
Of course, I’ve never read any of the books more than 50 pages into them because I hate Tolkein’s writing style (nor have I actually read the spoilers in this thread for that matter), so my vision of the ending might be a bit off…
Elfkin, people have been burned at the stake for lesser heresy.
