Speaking of fairly small changes that irked me. I know it seems fairly petty but the fact the PJ included Merry in the company of the Men of the West was rather irksome. I remember leaving the theater rather annoyed at it. It was one of those simple things that they didn't need to do and yet did.
The Mouth of Sauron bit was explained masterfully by Boromir so I will not go into that here. However there is at least one other thing that bothered me, that is when Sam is sent packing by Frodo. There love was too great for that to ever happen. I just don't agree with that bit at all.
Finally--Faramir.
Overall though I am grateful to PJ and crew because I feel that they did a wonderful job but there are a couple of things that I would change, but of course it wasn't my decision.
