I only had one real objection to the changes made to the plotline - Hasty Ents? The rest worked for me. What a very pretty movie.
Eowyn was good but was notable for the amount of acting she was obliged to do with practically no lines to do it with.
Will there be a Pippin and palantir scene? The set up is so different now.
Legolas 'skateboarding' was quite amusing.
I only noticed it because I saw it in the exhibit, but I still really like Grima's necklace.
On a related tangent: today I received a one true ring melting in the fire of Mount Doom. I have my very own mini Mount Doom now.
