Heh, I started a thread and then didn't have a chance to go online and respond for over a day...oh well...
I agree with Jedimark. Comparing Harry Potter and LOTR is an insult towards Tolkien. Harry Potter is not really special...little put them apart from other books in general. Some years ago you had Narnia which was mostly the same thing...
LOTR was a life's work, not written as a "book", just as a tale from a world that Tolkien had created and documented...The cultures in the book can be tracked back 10 000 years, all the languages has developed as they would have in reality, ALL names in the book has a root somewhere and some meaning... the world described just has an incredible depth. Even if you HATE the story, HATE the world itself, one can admire how it demonstrates principles of creating something (Tolkien called it sub-creation). It shows that Tolkien was a professor in this stuff...
About the ending... the ending of LOTR has furious battles and action...it just all happens inside of Frodo and Sam, so it's not visible on the surface. This makes it even better in my opinion, not because I necesarrily get very much enjoyment from reading about Frodo's internal struggles but because it's a much more epic way to finish something than a simple swordfight or whatever. There is action other places in the book, simply running those in reprise wouldn't have sufficed...also such a storyline would have been impossible. Rewriting that end into something more "interesting" (say, Sauron in a swordfight against Frodo, yeah, everyone who has read the books will laugh about *that* picture) would alter the entire premises of the book and it would have to rewritten from scratch (together with some 2000 years of Middle-earth history) because in the setting of the book something like that just wouldn't have been believable (doing something like that would have degraded the book into a regular fantasy book that we see so many of in the stores now (apologies to R. Jordan fans that I know are in here, but I don't really feel like comparing Tolkien and Jordan...perhaps Harry Potter and Wheel of time can be compared in some strange way, better than comparing LOTR and Harry Potter at least)).
The road towards the volcano at the end is the end of the world as it was known then (in that setting). Destroying the ring destroyed Sauron, it made the elves leave...changing the course of Midgards history in a way that could be compared to us making contact with aliens...the historical perspective in that ending chapters alone should be enough action...
Everyone has different tastes though.
Another example is Frodo and Sam coming back to Hobsyssel...it might seem trivial compared to what they have been through until that point, however it has an enourmous symbolical value. I've heard that that scene wasn't cutted (unlike Tom Bombadil's forest, aarggh...) and that fact makes me more positive even to the first third of the filmatization.
What I like best about LOTR is actually how it tries to level itself a few notches above common Hollywood action (ok so the book was written before the Hollywood crap started to flood the market...)...it simply tries beeing epic in a deeper way than say, Titanic and Pearl Harbor and the utter piece of crap known as Gladiator.
I would say that Harry Potter is more pure entertainment. There is so much entertainment out there! Harry Potter just got lucky and happened to be the thing that replaced Pokemon in the children's life...
OK this was harsh against Harry Potter...and I did kinda enjoy the books (well, the two of them that I have read anyway). Comparing them to LOTR never even occured to me though.

I thought the world premiere was on 19th, they're talking about how Norway is going to be the second country showing it because of the time zone differences (they're showing it at midnight naturally
