Top 5...

[Pitchwife]

In addition to everything mentioned above,
5. Elves at Helm's Deep
4. that whole 'Arwen is dying' nonsense
3. Théoden about to spew green pea soup (aka The Exorcist at Edoras)
2. Gollum made cute rather than wretched+dangerous+pitiful
1. Frodo sending Sam away

[mormegil]

5. The shield surf
4. How annoyed and critical we all get with PJ's take (overall he did a good job yet we are pedantic all the same)
3. Where the crap is Glorfindel? Why would Arwen go out...WHY!!!!
2. Faramir turns quasi-corrupt
1. I have to agree with Pitch that the WORST thing is Frodo turning Samwise away the whole scene was absolute rubbish. It just made me want to vomit.

[PrinceOfTheHalflings]

1. No great scene with Saruman at Bag End!

2. Nutty Denethor.

3. Stupid Ents.

4. Uncertain Aragorn.

5. Too many battle scenes.

[Tuor in Gondolin]

I actually like the way Arwen was used in FotR as a
sort of ZenaArwen (rather sexy and gave her more to do and generally
kept Glorfindel's actions intact). But minus points for not having Frodo speak to
the Black Riders at the Ford of Bruinen:

By Elbereth and Luthien the Fair,
you shall have neither the Ring nor me.

Five worst bits
1) Gandalf physically assaults the Stewart (against the specific
ban on the Wizards interfering (see Unfinished Tales).
2) Screwing up my favorite LotR character (Faramir).
3) The Green Slime at the Pelennor Fields (makes pointless the
whole charge of the Rohirrim which, of course, was probably why
Tolkien limited the Army of the Dead actions).
4) The inept way PJ portrayed the charge of the Rohirrim. Instead
of in broad daylight it should have been like the book, start it in
dark, have Theoden give a bit of his book speech:

Arise, arise, Riders of Theoden
Fell deeds awake, fire and slaughter,
Spears shall be shaken, shields splintered,
Ride now, ride now, ride to Gondor!

He takes horn from Guthlaf and blows on it,
then charges ahead of the Eotheod as the sun begins to
come out and shines brightly on his shield.
5) The ridiculous way Merry and Pippin tricked Treebeard into
going to Orthanc. Why not have the ents vote to go there
and recite their marching song en route?

[mormegil]

Fair points Tuor on the Army of the Dead. That does annoy me and I had forgotten it. I would replace the shield surfing scene with that in order of things that bother me.

[Morsul the Dark]

1) Elves at Helm's Deep
2) Aragorn doesn't have the shards with him.
3)Frodo stamping out the fire at Weathertop
4)sends Sam away
5)(I know it's a difficult to portray on film but....)Frodo is WAAAY too whiny

[Tuor in Gondolin]

5)(I know it's a difficult to portray on film but....)Frodo is WAAAY too whiny

Compunded by Agent Elrond intimating to Gandalf that movie Frodo
has performed so well getting to Rivendell. (In the movie, exactly how?)

I know that this does not happen but I'm curious as to why this would be on your top 5 list as it seems rather minor.

[Galadriel]

4. that whole 'Arwen is dying' nonsense
[/QUOTE]

Tell me about it. The movie made me want to hate her (in the books I find her annoying because Tolkien compares her to Lúthien lol)

[Eomer of the Rohirrim]

1. Wargs were replaced with suicidal hyenas.

2. No Warg scene on the way to Caradhras (or was it Moria?) where they surround the fellowship, Gandalf kills a few, etc.

3. Ents, especially Treebeard, treated as boring and stupid.

4. Frodo/Sam/Gollum lembas saga

5. Giant flaming eyeball (can't believe no-one mentioned this yet).

[Lalaith]

1. Major characters given personalities diametrically opposite to how Tolkien created them...eg Tolkien-Theoden "kindly old man" while film-Theoden angry and bitter, in fact playing the role of book-Denethor;
meanwhile Denethor himself - a leader who in the book did his utmost to defend Gondor, ordering the beacons to be lit and the Arrow to summon Rohan: "tall, valiant, more kingly than any man that had appeared in Gondor for many lives of men") turned into a drooling Nero-esque sybarite.

2. Major characters who were not actually transformed were trivialised and made oafish (Gimli, Merry, Pippin) or embarrassingly wet and over-emotional. (Frodo, Eowyn)

3. The stupid Arwen-into-horse scene in TT (didn't actually mind the Arwen-on-horse in FotR)

4. The stupid Treebeard-tricking in TT

5. The stupid Arwen-is-leaving-then-dying thing in TT

1. Ents, especially Treebeard
2. Frodo/Sam/Gollum lembas saga
3. The stupid Arwen-into-horse scene in TT
4. Giant flaming eyeball
5. Elves at Helm's Deep

[skip spence]

Off the top of my head

5) Turning the horror-scenes of the book into action scenes (ie. Black Riders, The Balrog...)
4) The stupid action scenes, like Legolas' ridiculous shield surfing, his climbing of ridiculously big Olliphants, the Dwarf-tossing, Sam fighting with cooking ware etc...
3) Denethor the retard
2) Stupid Ents (they actually annoy me in the books too, maybe I should start a thread about pet peeves in the books too?)
1) Almost about the entire RotK. In fact, don't think I've ever managed to sit it through.
