My brother tirelessly tries to imitate the "Manflesh!" part. It gets kind of annoying but it tells me that my brother is more obsessed with LOTR then he will admit. (Yeah, my conversion was almost succesful!!)
Anyway, I love the scenery in this sequence, especially during the running since you get this flying feeling. (Especially in the theatre which is why they should bring LOTR to Imax
)
I think the first sign of Pippin's "growing up" is when he leaves his brooch. It is a clever idea and certainly not something Pippin would have thought of back in FOTR. He is becoming less of a fool although he still has his "stupid moments"
I like that this sequence contrasts the story of Frodo and Sam because the pace is certainly much higher. Which I think is good because otherwise this movie would really drag.
