More detail about Rotk EE scenes (spoilers!)

[Tuor of Gondolin]

The way PJ handled the Army of the Dead is beyond much reclamation (it was absurd, presumably done for cgi purposes and to save movie time, by not having south Gondorians and Dunedain involved) but.........

If the above is correct there are numerous improvements
1) For once, PJ and friends intelligently rearranged events to carry the gist of the confrontations with Saruman at Orthanc and the Shire, rather smart to replace his killing Lobelia's son with Theodred)
2) There is at least a minimum of significance now to the charge of the Rohirrim (saving Gandalf), since in the theater version the Ghostbusters green slime could have destroyed Sauron's boys anyway, without the Rohirrim.
3) Numerous nice bits of Frodo and Sam's trek seem to be in.

This is an example of a meaningful addition in a dvd to a theatrical release.

[Encaitare]

Aragorn tells him you shall speak for Sauron no more and gets into a sword fight with him. Aragorn wins by slicing the mouth of Saruon's head.

It's all about Aragorn, isn't it? I love that scene so much, Gandalf's "These we shall take!" upon the hearing of the Mouth of Saruon's terms --and he seizes the cloak and mithril coat-- "These we shall take, in memory of our friend!" (This is not exact, I'm sure, as I'm working from memory!) I love it how it sounds as though he's accepting the terms and Pippin, I think it is, is thinking along the lines of "What the fork is he doing?" but then of course, he rejects them. It shows how Gandalf has his priorities and he puts his duties to Middle-earth above everything, even the life of a close friend.
