[Shards of Narsil]

Yes, it is difficult to pick since there are so many scenes that evoke so many different reactions. I try an think back to the first time that I saw each movie in the theatre, and I remember one instance where they showed the first scene of the Rivendell valley and I burst out "that's exactly how I imagined it in the books", so that is one of my favorite scenes for scenery (funny!).

The charge of the Rohirrim is definitely pretty good.

I also enjoyed the lighting of the beacons.

One scene that I don't think was previously mentioned was the attack of the Ents. I found it quite moving as Treebeard laments the fact that this would be the last battle of the Ents as they march to their doom.
