Probably true. My wife, for instance, really like the lines Eowyn did have in that scene ("I am no man!" prompting spontaneous praise, which is very unusual for her).
But that doesn't invalidate a lot of barsoomcore's complaints; I think they're quite valid. That scene should have been one of the big emotional payoffs of the movie, and it played out quite flat, IMO. And even though a strict Tolkien reproduction would undoubtably have been a poor move, replacing it with generally inferior dialogue wasn't exactly a great move either.
It's my opinion that Peter Jackson and Co. aren't really particularly gifted film-makers in a lot of ways, and the fact that the Lord of the Rings movies are as good as they are is more a testament to the strength of the source material than to their ability to adapt it. Especially as the movies went on, I noticed that the better scenes were the ones that were most like Tolkien. A particular gripe of mine is the non-Tolkien dialogue that simply rang artificial and unsatisfying. I was also particularly tired of the "slow motion emotional set pieces" as I call them; the scenes where you have a slow motion close-ups of characters seeing other characters give unnatural, posed and strained (yet very meaningful) looks to each other. Then character A, back to full screen slow motion close up, gasps and lets a single tear fall down his or her cheek. Then someone says something awkward.
Granted, I sound a bit schizophrenic in that post; I do agree that Tolkien needs some serious trimming and reshaping to be viable as a movie script. However, I also think that the Jackson adaptation, in a lot of ways, was a hack job where a more skillfull hand would have done better. Saying that Tolkien needs to be pruned to be a good movie and then turning around and saying that the best scenes in the movies were the largely untouched scenes is not contradictory, although it seems like it up front. It just means that Boyens and Walsh weren't really the best ones to write the screenplay. I think there are others who could have done a better job with the dialogue and the faux meaningful scenes.
And some of the introduced "conflicts" really felt forced and unusual. I can see what they were trying to do with the Sam and Frodo falling out, and Gollum's lembas crumbs, but that whole scene felt really hoaky to me. Of course, the slow motion falling crumbs, and slow motion stumbling Sam, and slow motion crying Sam and slow motion sneering Gollum, etc. didn't help.
Maybe I just really dislike some of the dialogue and the overuse of slow motion posed scenes for "emotional impact." Trust in the emotional impact of the source material, without constantly overdoing one attempted dressed up emotional sucker punch after another, please.
